MattssonandClaude Fable 5 f216a60bf8 feat(invoices): per-line percentage discount and separate fakturamarkning (#2084)
* feat(invoices): per-line percentage discount and separate fakturamarkning

User request: rabatt i procent per artikelrad, and a marking field
separate from Er referens.

- invoice_items.discount_percent (0-100, default 0): line_total and
  vat_amount are stored NET of the discount. Shared exact-ore math in
  lib/invoices/line-amounts.ts (gross, discount, net) used by the web
  builder, staged-operation commit, editor preview, PDF, and Peppol.
  Undiscounted lines keep the legacy unrounded qty*price byte-identical.
- ROT/RUT deduction computes on the discounted net line total.
- invoices.invoice_marking: printed on the PDF next to the references
  and mapped to Peppol BT-10 BuyerReference (marking wins over
  your_reference; either satisfies the BT-10 requirement).
- Peppol renders the discount as a BG-27 line AllowanceCharge
  (reason code 95, MultiplierFactorNumeric, Amount, BaseAmount).
- Editor: "Lagg till rabatt" in the row menu (same reveal pattern as
  ROT/RUT), Markning row next to Er referens, forval chip, review
  dialog shows discounts and marking.
- Plumbed through v1 REST projections, MCP create/get/update invoice
  tools, pending-operations update path, and copy-invoice (discount
  copied; marking deliberately not, it is recipient-specific).

* fix(invoices): carry discount_percent through every deduction, credit, convert and preview path

Skeptic + CI findings on the discount/marking feature, one pass:

- generateRotRutLines and propose-send-lines now pass discount_percent
  into computeDeduction: the send/credit/cash verifikat booked 1513 on
  the GROSS line while deduction_total, the PDF and the Skatteverket
  claim carried the net, stranding the difference on 1513 and pushing
  1510 negative once the customer paid. Test pins 1513=3000/1510=7000
  for a 20%-discounted 10 000 kr ROT line.
- preview-pdf route accepts discount_percent (net totals + net-based
  deduction) and invoice_marking; the editor now sends the marking, so
  the preview equals the invoice it becomes.
- Credit notes carry discount_percent (buildCreditNoteItem, v1 credit
  route select+insert, MCP credit executor) and invoice_marking, so the
  kreditfaktura face arithmetic multiplies out and shows the Rabatt
  column (ML 17 kap 24 §).
- Proforma->invoice convert copies discount_percent + invoice_marking:
  the converted invoice previously failed Peppol LINE_TOTAL_MISMATCH
  and lost the rebate on the next builder pass.
- Editor hides the discount menu in self-billed mode (the self-billed
  wire shape has no discount; previewed net would book gross).
- MCP staging and commitCreateInvoice reject a non-number
  discount_percent (a string coerced past the range check but was
  ignored by the totals math and still stored).
- Regenerated skills/accounted-api (apiskill:check CI failure).

17caf9d80a feat(mcp): article-aware invoice updates with gnubok_get_invoice round trip and rebooking preview (#1993)
* feat(mcp): article-aware invoice updates with gnubok_get_invoice round trip and rebooking preview

gnubok_update_invoice items are a FULL REPLACE, had no article fields, and
no MCP tool returned invoice lines, so a quantity fix rebuilt from memory
wrote article_id/revenue_account null and reverted vat_rate to the customer
default: revenue silently moved from the article account (3041) to the
VAT-derived default, invisible in the approval preview.

- gnubok_get_invoice (invoices:read, search-only): header plus every line
  with article_id, revenue_account, vat_rate, dimensions, editable_draft
- gnubok_update_invoice lines accept article_id with the same prefill and
  default-set VAT adoption guard as create; permitted-set VAT gate at
  staging; preview carries the new lines' effective booking and a snapshot
  of the lines being replaced
- commitUpdateInvoice scope-checks staged article ids like create does
- OperationPreview: update_invoice preview (current vs new lines, header
  diffs, totals); create_invoice lines show VAT rate and posting account
- invoicing skill points at the read-before-replace round trip

Closes #1642

* fix(mcp): use roundOre for update-invoice preview totals so the ore ratchet stays at baseline

The preview-building code in gnubok_update_invoice introduced five naive
Math.round(x * 100) / 100 occurrences, tripping check:guards
(naive-ore-round 627 vs baseline 622) and failing Core Build on PR #1993.
roundOre from @/lib/money is the sanctioned helper and was already
imported in this file.

* fix(mcp): make the invoice round trip lossless for text, ROT/RUT and accrual lines

Skeptic review of #1993 found three round-trip breaks for web-created
drafts edited via MCP (the exact silent-loss class issue #1642 reports):

- Text rows: the update pre-gate and resolveInvoiceLineFromArticle
  rejected quantity <= 0 before looking at line_type, so any draft with
  a free-text spacer row could not be edited at all, and the natural
  agent recovery (drop the row and retry the FULL REPLACE) silently
  deleted invoice content. Text rows are now exempt from the
  quantity/description/unit/price gates (CreateInvoiceItemSchema
  parity), normalized to the zeroed stored shape, excluded from the
  staged totals and the VAT gate (commitCreateInvoice billableItems
  parity), and line_type is declared on both the create and update item
  schemas.

- ROT/RUT: gnubok_get_invoice omitted housing_designation,
  apartment_number and brf_org_number, so an items replace on a ROT
  draft either failed AFTER approval ('Fastighetsbeteckning krävs för
  ROT-avdrag') or, for a schema-conformant agent, silently stripped the
  avdrag and the stored personnummer. The three property columns
  (property identifiers, never the personnummer ciphertext) are now
  returned per line, the deduction fields are declared on the update
  item schema, deduction_type rides on the current_items snapshot and
  the new-lines preview, and a staging-time completeness gate
  (arbetstyp/timmar via validateDeductionLines, fastighetsbeteckning
  for ROT, personnummer availability on the invoice or the individual's
  kundkort) surfaces the failure to the agent instead of the approver.

- Declared-schema gap: revenue_account and the accrual fields were
  accepted on pass-through but undeclared, so a schema-conformant agent
  dropped a manual posting-account override or a periodisering on
  pass-back. They are now declared on the update item schema
  (revenue_account also on create; create deliberately does NOT declare
  deduction/accrual fields because commitCreateInvoice drops them), and
  the approval preview shows ROT/RUT-avdrag and the periodisering
  period per line.

tools/list ceiling check after the two new create-schema properties:
63337 of 63400.
