fix(invoices): bank match stores the applied amount, not cash received, in invoice_payments (#2277)

* fix(invoices): bank match stores the applied amount, not cash received, in invoice_payments

The dashboard match-invoice route, its v1 twin and the pending-operation
match_transaction_invoice executor wrote invoice_payments.amount as the
cash received in invoice currency. When a whole-krona bank line settles an
öre-carrying remaining (the customer pays the rounded "Att betala"),
planInvoicePayment advances paid_amount by the remaining only and books
the öre on 3740, so the row exceeded the receivable by the absorbed öre:
remaining 999.60, bank 1 000.00 gave a 1 000.00 row against a 999.60
paid_amount. The kontantmetod cut-off then pushed a -0.40 receivable with
negative scaled moms, the historical AR ledger showed -0.40 outstanding
on a paid invoice, and a storno of the payment voucher restored
paid_amount 0.40 off (issue #2250).

PR #2236 defined the amount for the manual, MCP and Stripe paths as the
amount APPLIED to the invoice (new paid_amount minus the prior one). The
three bank-match paths now share that definition through one helper,
appliedPaymentAmount() in lib/invoices/invoice-payment-row.ts, which
recordInvoicePaymentRow() uses as well. Every other field of the row
(payment date, currency, exchange rate, journal entry, bank transaction,
notes) is unchanged. Without a residual the applied amount equals the
cash received, so ordinary matches post identical rows; cross-currency
rows are now öre-rounded like paid_amount instead of the 4-decimal spot
conversion, so row and paid_amount agree.

Existing rows carrying the overshoot are not repaired here; that is a
separate call.

* refactor(invoices): one writer for invoice_payments rows

Rework of the #2250 fix from first principles. The bank-match paths did
not just get the amount wrong; the class of bug is that invoice_payments
rows were hand-built at five product sites (dashboard bank match, its v1
twin, the pending-operation match, the link-to-existing-voucher flow, and
the #2236 paths through the helper), each computing its own fields with
no single definition of what the row means.

recordInvoicePaymentRow() (lib/invoices/invoice-payment-row.ts) is now the
one writer. Its options grew by what the bank paths set, all optional with
today's defaults so the #2236 callers are unchanged: transactionId
(default null), exchangeRate (the rate actually used; omitted =
invoice.exchange_rate, explicit null stored as null) and notes (default
null). The failure result carries the Postgres SQLSTATE so the routes keep
mapping a unique violation (23505) exactly as before. The applied-amount
formula is an internal detail of that file again.

Routed through the writer: app/api/transactions/[id]/match-invoice, the
v1 match-invoice twin, commitMatchTransactionInvoice in
lib/pending-operations/commit.ts, and lib/transactions/link-journal-entry.ts
(strict plan, same currency only: its amount is unchanged, it now shares
the row semantics). The pending-operation path used to drop the insert
error on the floor; it stays non-fatal but is logged with ids.

Guard: scripts/checks/no-new-antipatterns.mjs gains
direct-invoice-payment-insert, a file-set rule with no baseline (0 today):
.from('invoice_payments').insert( or .upsert( anywhere under app/, lib/ or
extensions/ outside lib/invoices/invoice-payment-row.ts fails
npm run check:guards. Operator scripts under scripts/ are out of its scope
on purpose.

Tests: the writer's unit tests cover the new options, the explicit-null
rate, the SQLSTATE passthrough and the öre-rounded prior-paid
subtraction; the per-path 3740 tests from the first commit stand; mock
insert slots now return the row id the writer selects back.
