Jakob Wennberg 4a38fa30ed fix(recon): share the cash-account scope and cover the no-1930 case (#1309)
PR #1295 (144cc514) fixed computeVatCloseCheck on main while this branch was
fixing it a second, different way. This rebuilds the branch on top of that
merge instead of re-landing the duplicate: main's local
getScopedReconciliationStatus stays as the MCP entry point, its lookup body
moves into lib/reconciliation/cash-account-scope.ts, and the pieces main does
not have are added on top.

Why the lookup has to live in lib/: the bokslut readiness aggregator has the
same defect and is core code, which must never import from @/extensions/. It
called getReconciliationStatus with 4 positional args, so cashAccountId stayed
undefined and scopeTransactionsToAccount fell through to its currency-only
filter: the bank side summed every SEK cash account while the GL side stayed on
1930, and the wizard reported "Bankavstamningen visar en differens" with zero
unmatched transactions and zero unmatched GL lines to point at. Same shape as
the MCP blocker in #1290, different surface.

Decisions taken deliberately, not by taking 'ours':

1. Lookup errors fail CLOSED, everywhere. resolveCashAccountScope throws
   "Kunde inte hamta kassakonto <n>" instead of returning the unscoped
   fallback. The earlier version on this branch logged and fell back, which
   turned a transient DB error or an RLS denial straight back into the #1290
   pooling path. Main's contract wins; its merged test asserting exactly that
   still passes untouched.

2. The default resolution no longer hard-codes 1930. With no account_number
   argument the resolver tries 1930 and, only if the company has no such row,
   falls back to its primary cash account. Measured read-only on prod
   2026-07-30: 2 companies have no 1930 cash_accounts row while running two SEK
   cash accounts each and zero journal_entry_lines on 1930, so the check
   compared their entire SEK bank volume against an empty GL side, i.e. a
   high-severity bank_unreconciled blocker with count 0 that no user action
   could clear. Roughly 20x the difference the issue reported. A caller that
   NAMES an account gets no fallback, so gnubok_get_reconciliation_status still
   rejects "Okant kassakonto 9999" rather than silently answering about a
   different account. 1367 companies have a 1930 row and are unaffected,
   including the 5 whose 1930 row is not the primary one.

3. The blocker message names the resolved account instead of a literal 1930:
   pointing a user at 1930 when the reconciliation ran on 1935 sends them to an
   account with no lines on it.

4. warnIfUnscopedAcrossCashAccounts logs a warning when a run left
   cashAccountId undefined AND the rows it fetched really do span more than one
   cash account. Kept on the write path too: an unscoped runReconciliation can
   persist a wrong journal_entry_id, which does not clear itself later.

Duplicate regression suite collapsed: the branch's
vat-close-check-bank-scope.test.ts overlapped main's
vat-close-check-reconciliation-scope.test.ts case for case, so only the cases
main lacked were merged into main's file (the primary-account fallback, the
message naming the resolved account, the blocker still firing on a genuine
scoped difference, and the tool handler's own scope resolution).

Residuals are now tracked issues, not code comments:

- #1298: the post-sync runReconciliation sweeps in
  app/api/extensions/enable-banking/sync/cron/route.ts and
  extensions/general/enable-banking/index.ts still run unscoped. They are write
  paths.
- #1299: booked transactions with a NULL cash_account_id whose verifikat has no
  line on the primary account still inflate the bank total. Measured all-time
  on prod: 294 booked NULL rows, 22 of them on verifikat with no 1930 line,
  4 companies, net -4170.31 kr with monthly swings from -18055.82 kr to
  +38086.00 kr. Fixing it means finishing the cash_account_id backfill.

Also: the file-global logger mock in bank-reconciliation.test.ts now wraps the
real module and swaps only warn, instead of substituting a four-method stub
whose child() returned undefined for the entire module graph of that suite.

Verified: npx vitest run over lib/reconciliation, lib/bokslut,
extensions/general/mcp-server, app/api/reconciliation, app/api/extensions,
app/api/v1, app/api/bookkeeping, app/api/transactions, lib/pending-operations,
lib/bookkeeping, lib/invoices, lib/transactions, lib/reports: all green.
eslint on the 8 changed files: 0 errors (18 pre-existing unused-import
warnings in server.ts). tsc --noEmit: 405 errors, byte-identical to the
origin/main baseline. check:guards passes. No migration, so no pg-real test.

Fixes #1290
