Whole-krona Bankgiro/Swish payments of öre-bearing invoices were stranded
as partially_paid forever (e.g. 11 231 paid on an 11 231,25 invoice left
0,25 kr open). Book the sub-krona residual to BAS 3740 (Öres- och
kronutjämning) and settle the invoice in full, on both the supplier- and
customer-invoice match flows.
New shared pure helpers buildSupplierPaymentClearingLines +
planSupplierPayment mirror the customer-side primitives; routing preview
and commit through the same builder also fixes two pre-existing
preview↔commit drifts (payment account + line descriptions). Öre
absorption is accrual-only — cash entries book the full invoice, so
absorbing there would hide a 1930 discrepancy.
Also improves supplier-invoice ↔ bank matching:
- Pass-3 date window now spans [invoice_date-5, due_date+5] instead of
due_date ±5, so early payments auto-match; an ambiguity guard demotes
non-unique amount matches to suggestions.
- New retroactive matcher (on supplier_invoice.registered/.approved)
surfaces the settling bank payment when the invoice is registered after
the payment was imported. Matches are written as suggestions for
one-click confirm-to-book, never silently auto-booked.
Tests: new unit tests for both pure helpers; extended matching, handler,
customer öre, and route suites. Full suite green (407 files / 5364 tests).
