* feat(invoices): offert to kundorder, the missing step in offert, order, faktura

"Skapa order" on an open or accepted quote creates a draft kundorder from
its lines. The quote stays as the customer's accepted agreement (flips to
quote_status accepted with a compare-and-set on the decision that was
read); the order is delivered and invoiced, in full or in parts, from the
kundorder page. Declined quotes are refused. Same action on the MCP side:
gnubok_convert_invoice takes target 'order', staged under the existing
convert_invoice operation type.

Why the problem occurred: the proforma -> order conversion refused every
source that was not a proforma, so the offert, which is what users
actually send before an order, could only become an invoice. The product
had both ends of the Fortnox flow (offert, kundorder) but no bridge.

What was removed or simplified: no second service and no new operation
type. The proforma conversion became the document conversion
(lib/sales-orders/convert-to-sales-order.ts) with the quote source as a
branch on the source update, mirroring how convertToInvoice already
treats the two. The MCP surface is one tool with a target parameter
rather than a sibling tool, which also gives proforma -> order the MCP
surface it did not have.

Why this shape: the sale must never exist twice. A quote with a live
converted invoice cannot become an order (INVOICE_QUOTE_ALREADY_INVOICED),
and a quote with a live kundorder cannot become an invoice a second time
(new INVOICE_QUOTE_ALREADY_ORDERED: invoice from the order instead). A
cancelled order or invoice frees the quote again. Rejected: cancelling the
quote like the proforma path (hides the accepted agreement), a separate
gnubok_convert_quote_to_order tool, and refusing expired quotes (the
invoice path allows them behind a confirm; the order path does the same).

Fixes #2224

* fix(sales-orders): hold the one-sale-per-quote guard in the database and fail closed on a missing FX rate

Skeptic refutations on the offert -> kundorder change:

1. An already-accepted quote could be converted twice concurrently (two
   orders, or an order and an invoice): the services' pre-checks are not
   serialized and the accepted -> accepted compare-and-set matches for
   every caller. Migration 20260908152555 adds a partial unique index
   (one live kundorder per source document) and two BEFORE triggers that
   lock the quote row and refuse a live order beside a live converted
   invoice and vice versa, so concurrent conversions queue and the second
   one sees the first. The services map the raised codes onto the same
   409s the pre-checks use. pg-real test covers the index, both
   directions, reopen from cancelled, the member-session lock, and the
   concurrent pair on two connections.

2. createInvoiceFromSalesOrder booked a foreign-currency invoice with a
   NULL exchange rate when Riksbanken had none, which resolveSekAmount()
   then posts 1:1 as kronor. Pre-existing, but the quote now depends on
   the order path and the fail-closed quote -> invoice route is refused
   while an order lives. The order path now fails closed with
   SALES_ORDER_INVOICE_FX_RATE_UNAVAILABLE, like convertToInvoice.

* fix(pending): describe the kundorder outcome when approving a convert_invoice staged with target order

The approval dialog's consequence sentence was keyed on operation_type
alone and promised a faktura with F-number for every convert_invoice.
With target 'order' the commit creates a draft kundorder and books
nothing, so the sentence now reads the params (skeptic refutation).

* fix(invoices): lock the quote decision behind a live kundorder, run the guards as definer, name the offert on the order page

Correctness skeptic refutations on the offert -> kundorder change:

1. A quote with a live kundorder could still be set to open or declined
   (dashboard route, v1, MCP): the decision guard only knew converted
   invoices. The dashboard then hid the re-accept button, so the quote
   was stuck as "Avböjd" behind a confirmed, invoiced order. Migration
   20260908155231 extends invoices_quote_decision_guard to refuse leaving
   accepted while a live kundorder points at the quote
   (INVOICE_QUOTE_ALREADY_ORDERED); the three writers map the code.

2. The two source guards from 20260908152555 locked the quote row with a
   SELECT FOR UPDATE as the invoker. Under RLS that also applies the
   UPDATE policy, which admits only the caller's active company, so a
   multi-company member writing for another company through raw
   PostgREST got no row, no lock and no guard. All three guard functions
   are now SECURITY DEFINER. pg-real test covers the non-active company
   and the decision lock.

3. The kundorder page labelled every source "Proformafaktura". It now
   loads the source document and shows "Offert OF-nnn" for a quote; the
   MCP field description and the type comment say proforma or quote.

* fix(mcp): keep tools/list under its token ceiling and refuse cross-company sources in the definer guards

CI: the target parameter and two description edits pushed the projected
tools/list payload to 60 502 tokens against the 60 500 ceiling; the same
facts now fit in fewer words (ceiling unchanged).

Superagent P2: the source guards run as definer since 20260908155231, so
a source_invoice_id or converted_from_id pointing at another company's
document would have locked and inspected that row. Both guards now
require the source to belong to the row's company and refuse otherwise
(SALES_ORDER_SOURCE_COMPANY_MISMATCH / INVOICE_CONVERT_SOURCE_COMPANY_MISMATCH),
covered by a cross-company pg-real case. Migration 20260908155231 was
re-applied to staging under the same version (never on prod).

* chore(migrations): move the quote conversion guards to versions after main's 20260908164944

Main merged a later version while this branch was open; Supabase applies
pending versions in order, so both files are renamed to fresh versions
(20260908165000, 20260908165100) and re-tracked on staging under those.
Byte-identical SQL.

MattssonandClaude Fable 5.1 1c82baf553 feat(invoices): offert (quote) document type with own OF-series, decisions, conversion, MCP and v1 (#2163)
* fix(invoices): reminders, AR ledger, AR reconciliation and deadlines only read fakturor

The overdue-reminder run, the kundreskontra, the 1510 reconciliation and the
deadlines page selected invoices by status alone. A sent proforma past its
due date was chased with a betalningspaminnelse and flipped to 'overdue',
and it appeared as a receivable. All four now filter document_type =
'invoice', which is also the precondition for adding quotes (offert): a
quote carries a date but never a receivable.

* feat(invoices): offert (quote) document type with its own OF-series, decisions and conversion

Adds document_type 'quote' with valid_until, quote_status (open / accepted /
declined; expired is derived from valid_until, never stored) and
quote_decided_at. Quotes are numbered OF-nnn at insert from
company_settings.next_quote_number via generate_quote_number(), the same
pattern as delivery notes, so a declined quote never leaves a hole in the
F-series the way a proforma does. The column next_quote_number already
existed on prod and staging without a migration; the migration adopts it.

Engine: build-invoice-write writes the quote columns and keeps
remaining_amount at 0; the draft editor refuses accepted or declined
quotes; PATCH refuses changing a quote's or delivery note's document type
since the number belongs to the series; mark-paid refuses quotes.

New POST /api/invoices/[id]/quote-status records the decision and locks
once an invoice exists. Conversion is extracted into
lib/invoices/convert-to-invoice.ts (one implementation for the route and
the MCP staged commit, which had drifted): a converted quote stays and
flips to accepted, the invoice links back via converted_from_id and gets
its due date from the customer's payment terms; a declined or already
invoiced quote is refused. next-number previews the OF-series for quotes.

Migration applied to the staging branch and registered as 20260902140000;
the pg test runs in CI (pg-real).

* feat(invoices): quote PDF, email and filename surfaces

The customer-facing surfaces get a quote sibling for every proforma branch:
PDF title OFFERT / QUOTE with Offertdatum and Giltig till instead of the
due date, a notice that the document is not an invoice or a payment
request, and no payment box, OCR, bankgiro, Swish, QR or payment link.
The email says the quote is attached and valid until the expiry, drops
the payment details and pay-online button, and asks about the quote
rather than the invoice. Filenames read "Offert nr OF-001". Seller VAT
number and payment accounts are skipped for quotes as for proformas:
a quote is not a faktura under ML 17 kap.

* feat(invoices): offert in the editor, list and detail pages

Editor: "Offert" document type with a required "Giltig till" field
(default today + 30 days) in place of the due date; the wire body mirrors
it into due_date so the shared schema is satisfied. Payment link, ROT/RUT,
periodisering and the bank box are already gated on real invoices. The
type cannot be switched on an existing quote (its OF-number belongs to
the series).

List: an Offerter tab beside Proforma, "Ny offert" in the split button,
and a status column that shows the decision or the derived expiry:
Utgången and Avböjd are exception chips, Öppen and Accepterad muted text.

Detail: Acceptera and Skapa faktura in the header, Avböj in the overflow
menu; an expired quote asks before accepting or invoicing (bypassable);
once an invoice exists the page links to it as Fakturerad and hides the
decision actions. Strings in both sv and en.

* feat(mcp,v1): expose offert on the MCP tools and the v1 REST surface

MCP: create_invoice takes document_type quote with a required valid_until
and allocates the OF-number at insert; the convert tool keeps its id and
accepts quotes with the registry refusal codes; new set_quote_status;
list_invoices and get_invoice expose valid_until and the effective quote
status, including a derived expired filter. The tools/list payload stays
under its ceiling without a ledger change. The MCP staged convert now
uses the shared converter.

v1: POST /invoices/{id}/quote-status (registered in the endpoint registry,
scope map and route loader), valid_until and quote_status in the list,
create and detail shapes, and a quote_status list filter. Skill atoms
mention offert. Decision log lines for the own number series, derived
expiry, accepted-not-cancelled conversion and the header action layout.

* refactor(invoices): literal update payloads in the converter so the phantom-column guard can read them

* fix(invoices): close the quote review findings in one pass

Skeptics (correctness, compliance, regression) and CodeRabbit on #2163:

- quote_status is no longer a write-builder output, so a v1 PATCH or MCP
  update_invoice can never reset a recorded accept/decline; new quotes are
  opened by the invoices_quote_defaults trigger (20260902141000), which
  also keeps due_date and valid_until equal. v1 PATCH and the MCP update
  executor now use the shared editable-draft predicate.
- One live invoice per converted source, enforced by a partial unique
  index; the converter maps 23505 to INVOICE_QUOTE_ALREADY_INVOICED and
  both quote-status routes compare-and-set on the decision they read.
- MCP-created quotes carry remaining_amount 0; mark-paid, transaction
  match and voucher link refuse non-invoices on the MCP staging tools,
  the executors and the dashboard link route.
- Conversion of a foreign-currency source refetches the rate for the
  conversion day (ML 8 kap 21-23 paragraphs) and fails closed without one;
  0-day payment terms mean due on receipt.
- bulk-create refuses quotes per item; list_invoices rejects a
  quote_status filter combined with another document_type; an omitted
  document_type on PATCH means unchanged.
- attention, push notifications, open-AR count, FX revaluation, year-end
  and accrual auto-detect and bank-match suggestions only read fakturor.
- Quote PDF and email print Summa / Total instead of Att betala.
- Regenerated skills/accounted-api for the new v1 endpoint.

Declined with reasons in DECISIONS.md: NOT VALID + VALIDATE and CONCURRENTLY
on the migrations (repo precedent, 13.8k rows, transactional apply);
re-validating VAT treatment at conversion (the converted invoice is a
draft the user reviews; follow-up).

* fix(invoices): second review round: migration versions, order links, batch allocation, races

- Migrations renamed to 20260902220000 / 20260902221000: #2166 shipped its
  own 20260902141000 to prod while this PR was in review and prod's head
  moved past both files; below-head versions are skipped by branching,
  which would have left the quote trigger off prod. Staging rows renamed.
- Quote lines never carry sales_order_item_id (an offer must not count as
  invoiced kundorder quantity); the converter carries a proforma line's
  order link onto the invoice.
- Converter compare-and-sets the source (proforma cancel, quote accept):
  a concurrent cancel, proforma-to-order conversion or decision removes
  the orphan invoice with INVOICE_CONVERT_SOURCE_CHANGED instead of a
  second document for the same sale.
- MCP set_quote_status gets the same compare-and-set as the HTTP routes;
  0-row updates report INVOICE_QUOTE_CHANGED_CONCURRENTLY everywhere.
  quote-status (dashboard, v1, MCP) accepts valid_until so an expired
  sent quote can be reopened, as the docs promised.
- MCP mark-paid refuses only quotes, parity with the dashboard route
  (a sent proforma marked paid is a supported prepayment record).
- Batch allocation (dashboard route and MCP tool) refuses non-invoices
  before the RPC, which gates on status alone.
- Customer AR drill-down, v1 customer open invoices and archive guard,
  and the calendar feed read fakturor only.
- Draft quote PDF says "UTKAST" instead of "not a valid invoice"; the
  editor locks the document type on existing quotes and delivery notes.

* fix(invoices): third review round: atomic decision lock, viewer gate, lookup errors, quote payment terms

- 20260902222000: BEFORE UPDATE trigger locks an accepted quote while a
  live converted invoice exists (the compare-and-set in the three decision
  writers could still be beaten by a conversion landing in between); the
  routes and the MCP tool map the raise to 409 INVOICE_QUOTE_ALREADY_INVOICED.
  generate_quote_number now also requires a non-viewer membership so a
  viewer's session token cannot burn OF-numbers through PostgREST.
- Converter checks quote eligibility before the Riksbanken call and treats
  a failed company_settings read as a failure instead of a 30-day default.
- Re-sending the same decision keeps quote_decided_at (idempotent).
- gnubok_find_voucher_candidates_for_invoice refuses non-invoices like its
  write sibling; the dashboard link route surfaces a failed lookup.
- Late-fee and credit-term texts never print on a quote.
Applied and registered on staging; pg tests added.

* fix(invoices): review nits: fail-closed batch lookup, dry-run expiry, quote heading, quote-date CHECK

- match-batch surfaces a failed document lookup instead of allocating.
- v1 quote-status dry-run preview carries the new valid_until.
- Quote PDF heading reads Offertinformation / Quote information.
- 20260902222000 also pins the date invariants the trigger maintains as a
  CHECK: a quote always has valid_until = due_date, nothing else has one.
  Applied on staging.
