fix(transactions): stop defaulting supplier-invoice payment account to a stale private-funds setting (#985)

* fix(transactions): stop defaulting supplier-invoice payment account to a stale private-funds setting

match-supplier-invoice (POST + preview) defaulted the credited cash account
from company_settings.last_supplier_payment_account, a sticky setting written
by the manual mark-paid "betald med privata medel" flow. Once that setting
held 2893 (skuld till aktieägare) from an unrelated private payment, every
later match against a real bank transaction reused it instead of the
transaction's actual bank account, silently booking genuine bank payments as
shareholder-loan repayments.

Resolve the credit account from the matched transaction's own
cash_account_id -> cash_accounts.ledger_account instead (falling back to 1930
when unlinked), mirroring the existing settlement-account lookup in
transactions/[id]/categorize/route.ts. last_supplier_payment_account is no
longer read by either route.

* refactor(transactions): extract shared settlement-account resolution helper

Dedupe the identical cash_account_id -> ledger_account lookup across
match-supplier-invoice (POST + preview) and categorize into
resolveSettlementAccount, per CodeRabbit's nitpick on PR #985. Pure
extraction, no behavior change.

* test(transactions): cover settlement-account lookup-error and preview parity gaps

Adds the two test cases CodeRabbit flagged as missing on PR #985:
- POST match-supplier-invoice: cash_accounts lookup errors, falls back to
  1930 and warns (previously unexercised).
- preview match-supplier-invoice: linked cash account other than 1930
  (parity with the equivalent POST-route test).

* fix(transactions): thread resolved settlement account into FX/cash-method supplier-payment branches

Closes the remaining items from the Swedish-accounting-compliance bot
review on PR #985:
- match-supplier-invoice/route.ts computed paymentAccount via
  resolveSettlementAccount but only passed it into the pure-SEK clearing
  branch; the FX branch (createSupplierInvoicePaymentEntry) and
  cash-method branch (createSupplierInvoiceCashEntry) still defaulted to
  1930 internally even though both already accepted the parameter.
- resolveSettlementAccount now also warns (and falls back to 1930) when
  cash_account_id resolves to a row with no ledger_account, not just on
  a hard query error.
- Documents company_settings.last_supplier_payment_account's scope via
  a column comment: it must never be read to resolve a matched
  transaction's settlement account.

* fix(bookkeeping): abort instead of silently defaulting to 1930 when settlement-account lookup errors

Compliance-bot finding on PR #987 (applies equally to #985/#986, shared
helper): resolveSettlementAccount treated "no cash_account_id" and "lookup
threw a real DB error" the same way -- warn and fall back to 1930. An
explicit cash_account_id almost certainly resolves to a non-1930 account,
so a transient failure masking it risked the exact class of misbooking
this whole PR series exists to fix, just triggered by infra flakiness
instead of a stale setting.

Now throws BookkeepingDatabaseError on a genuine query error; every
caller already runs under withRouteContext/withApiV1 (or the pending-
operations dispatcher), whose existing catch-all already converts any
isBookkeepingError() throw into the correct structured 500 -- no caller
changes needed. The "row found but ledger_account empty" case stays
warn+fallback (data-integrity gap, not a query failure).

* test(bookkeeping): use rejects.toBeInstanceOf for settlement-account error assertion

Addresses CodeRabbit nitpick from the 2026-07-12 review round: matching
BookkeepingDatabaseError via a `constructor` key in toMatchObject is
non-idiomatic; toBeInstanceOf is the standard vitest assertion for this.

* docs: scope FX/cash-method paymentAccount gap note to /api/v1 and MCP routes

CodeRabbit flagged the #1000 reference on PR #985 as ambiguous — the main
match-supplier-invoice route's FX/cash-method branches already thread
paymentAccount (per the prior entry), so the still-open gap only applies
to the /api/v1 and MCP-facing route.

[2026-07-11] Hoisted local VAT checks + RC-gap worklist out of SkatteverketPanel into ungated VatChecksCard: the panel's paywall/not-connected early-returns hid compliance errors from exactly the users who file manually.
[2026-07-11] NE/INK2 amounts display in whole kronor (matches filed SRU values per SFL); momsdeklaration keeps öre (reconciles against ledger and settlement verifikat). Numbered h2 section headers instead of a stepper component on the VAT page: same sequencing legibility, a tenth of the diff.
[2026-07-12] Compliance-review triage on the payment-link PR: finding 1 (email pay button on kreditfaktura) verified FALSE: invoice-templates.ts derives isCreditNote from credited_invoice_id and hidePayment already gates both HTML and text builders; no change. Finding 2 was the real deferred v1 gap but misfiled against invoice-columns.ts (which already carries deduction_total): the actual hole was the v1 send route's hand-rolled fetch projection, now replaced with the shared INVOICE_FULL_COLUMNS/INVOICE_ITEM_FULL_COLUMNS so PDF/email inputs cannot drift from the GET shape again (closes the [2026-07-10] deferred ROT/RUT send fix; also gives v1 sends the pay button + deduction box). Finding 3 accepted as a robustness fix only: the non-ok path already reflected true server state, but a thrown fetch left the Godkann spinner stuck; approve handler now try/catch/finally with a server refetch on failure.
[2026-07-11] match-supplier-invoice (POST + preview) misbooked a real bank payment to 2893 (skuld till aktieägare) instead of 1930: both routes defaulted paymentAccount from company_settings.last_supplier_payment_account, a sticky setting only meant to remember the manual mark-paid "betald med privata medel" account choice. Once that setting held 2893 from an unrelated private payment, every subsequent real bank-transaction match reused it. Fixed by resolving the credit account from the matched transaction's own cash_account_id -> cash_accounts.ledger_account (falling back to 1930 when unlinked), mirroring the existing settlement-account lookup in transactions/[id]/categorize/route.ts. last_supplier_payment_account is no longer read by either route; it stays scoped to seeding the manual mark-paid UI's default picker. Did not touch the FX branch (createSupplierInvoicePaymentEntry, still defaults paymentAccount internally to 1930) or the cash-method branch (createSupplierInvoiceCashEntry, called with paymentAccount=undefined): both are pre-existing, separate gaps outside this bug's repro (a pure-SEK accrual match).
[2026-07-11] Extracted the cash_account_id -> ledger_account resolution (identical in match-supplier-invoice POST, its preview, and transactions/[id]/categorize) into resolveSettlementAccount (lib/bookkeeping/settlement-account.ts), per CodeRabbit's dedup nitpick on PR #985. Pure behavior extraction, no logic change. Investigated whether other transaction actions should adopt it: bulk-book/book already resolve the account client-side (components' shared resolveAccount in lib/cash-accounts/resolve-account.ts) before the manual lines reach the server, so no gap there. Found two real gaps left open, NOT fixed here (bigger surface, deserve their own review): (1) the customer-side match-invoice route (POST + preview) and the underlying createInvoiceCashEntry/buildInvoicePaymentClearingLines (lib/bookkeeping/invoice-entries.ts, invoice-payment-lines.ts) hardcode account_number: '1930' unconditionally, never reading cash_account_id at all, so any customer receipt landing in a non-primary bank account is misbooked, same defect class as this PR fixed but present unconditionally rather than only when a stale setting fires; (2) the /api/v1 (MCP-facing) match-supplier-invoice route still calls createSupplierInvoiceCashEntry/createSupplierInvoicePaymentEntry with paymentAccount left undefined (defaults to 1930 internally), i.e. the pre-#985 bug's underlying gap is reachable through the public API/MCP tool surface even after this fix merges. The v1 categorize route has the analogous gap: it never calls applySettlementAccount after building its mapping result.
[2026-07-11] Closed the remaining items from the Swedish-accounting-compliance bot review on PR #985: (1) the FX branch (createSupplierInvoicePaymentEntry) and cash-method branch (createSupplierInvoiceCashEntry) in match-supplier-invoice/route.ts were already computing `paymentAccount` via resolveSettlementAccount but not passing it through to those two calls (only the pure-SEK clearing branch used it) -- both functions already accepted an optional paymentAccount param (`paymentAccount || '1930'` internally), so this was a one-line threading fix per call site, not a new code path; the preview route already threaded it everywhere, confirmed by reading its cash/FX preview branches. (2) resolveSettlementAccount now also warns (and still falls back to 1930) when cash_account_id resolves to a row with no ledger_account, not just on a hard query error: a bound-but-empty ledger_account is a data-integrity gap, not a normal unlinked-transaction case, and previously fell back silently. (3) Added a column comment on company_settings.last_supplier_payment_account (migration 20260711140000) documenting that it must never be read to resolve a matched transaction's settlement account.
[2026-07-12] resolveSettlementAccount now throws BookkeepingDatabaseError('resolve_settlement_account', ...) instead of warning-and-falling-back-to-1930 when the cash_accounts lookup itself errors (an explicit cash_account_id almost certainly resolves to a non-1930 account, so a transient DB blip masking it must not silently misbook a real payment -- a failed request the caller can retry beats a wrong verifikat needing a storno). Left the "row found but ledger_account is empty" case as warn+fallback: that's a data-integrity gap, not a query failure, and a prior compliance-bot round only asked for a warning there. No caller changes needed: every route here already runs under withRouteContext/withApiV1, whose outer catch-all already converts any isBookkeepingError() throw into the correct structured 500 via errorResponse/v1ErrorResponse, and lib/pending-operations/commit.ts's dispatcher already has the identical generic bookkeeping-error handling for every other engine failure. Same change applied identically across #985/#986/#987 (shared helper file). Filed #1000 to track the still-open FX/cash-method paymentAccount gap in the /api/v1 and MCP-facing match-supplier-invoice route (the main match-supplier-invoice route's FX/cash-method branches already thread paymentAccount via resolveSettlementAccount, per the entry above; deliberately out of scope, matches this PR's own scope decision) and a new issue to track historical-mis-booking remediation (PR #986 compliance bot finding #3, a distinct detection/correction initiative never claimed in scope by any of these three PRs).
[2026-07-12] pain.001 salary dialect hardened to the Swedish Common Interpretation (Bankforeningen "Common Payment Types in Sweden" Appendix 1, Example 4 Salaries; cross-checked vs Nordea Corporate Access pain.001 examples v2.6, 2026-06-22): dropped SvcLvl SEPA (SEPA credit transfer is EUR-only; omitting SvcLvl gets the domestic NURG default), dropped RmtInf (Nordea: remittance info not allowed for SALA; statement text comes from the Dataclearing LON code), creditor addressed as CdtrAgt ClrSysMmbId SESBA + CdtrAcct Othr SchmeNm BBAN with the account WITHOUT clearing, Dbtr now carries OrgId, all ids clamped to Max35Text. The clearing/account split (Swedbank 5-digit shift, Nordea personkonto prefix dedup) is extracted to splitDomesticBankAccount in lib/salary/payment/bank-account.ts and shared by BOTH the bg-lb and pain001 generators so the two formats can never route a payment differently again (pain001 previously concatenated raw digits and duplicated the personkonto clearing). Swedbank MmbId = first 4 clearing digits with the 5th shifted into the account, mirroring the production-proven LB encoding and the appendix's 4-digit MmbId salary example; run a generated file through Swedbank Validex (and the other banks' test uploads) before the 1 Aug Bg Lon campaign.
[2026-07-12] ESG/CO2 reporting parked (no build): external revisor review flagged its absence; not a purchase criterion for the target segment (tech-native sjalvbokforare). Revisit on real customer demand; likely shape then is a spend-based CO2 estimate on supplier invoices as an extension, not core.
[2026-07-12] "Projektredovisning" split into two scopes after the revisor review: full project accounting (WIP, successiv vinstavrakning, budget follow-up) parked indefinitely; light time-to-invoice (time entries to invoice rows; schema support already exists via project_time_entries and dimension FKs) stays an OPEN 2026 positioning decision, deliberately not committed yet.
