feat(woo): mark an order as already booked outside the integration (#1895)

* feat(woo): mark an order as already booked outside the integration

Orders booked by hand before the store was connected sat under Att
bokfora forever: the only exits were the book and create-invoice routes.

- Migration: manually_booked_at/_by + optional
  manually_booked_journal_entry_id on webshop_orders (informational link,
  no financial freeze; the mark produced no accounting objects).
- POST/DELETE /api/webshop-orders/[id]/mark-booked: mark with optional
  posted-verifikat reference (validated per company), conditional claim
  against concurrent booking/invoicing; unmark is a plain revert.
- book and create-invoice routes refuse marked rows (409
  WEBSHOP_ORDER_MANUALLY_BOOKED) and exclude them in their atomic claims.
- List route: booked/unbooked filters treat a manual mark as a closed
  exit, so marked rows leave the Att bokfora tab and join Bokforda.
- Orders page: row overflow menu with Markera som bokford / Angra
  markering, MarkOrderBookedDialog with a searchable candidate list of
  posted entries near the order date, muted status text linking to the
  referenced verifikat.

Fixes #1879

* fix(woo): close skeptic findings on the manual-booked mark

- mark-booked applies the same open-twin gate as book/create-invoice:
  an OPEN legacy feed transaction blocks the mark (409
  WEBSHOP_ORDER_LEGACY_TRANSACTION_OPEN); ignored or booked feed rows
  unlock it, so no open path to a duplicate remains.
- ingest treats manually marked rows as frozen for drift purposes:
  remote financial deltas set remote_changed_after_freeze (same badge as
  booked rows) instead of silently refreshing the row under the user's
  assertion.
- re-marking with a journal_entry_id updates the informational link
  instead of silently dropping it.
- dialog: candidate amount computed from the returned lines (the list
  API does not return total_amount), newest-first ordering, cap hint.

* chore(migrations): bump webshop manual-booking migration past freshly merged 20260825120000

* fix(woo): resolve PR review findings in one pass

- freeze v3 migration: financial fields are frozen at the DB level while
  a row is manually marked as booked (review finding: the mark's freeze
  lived only in ingest.ts, so any other write path could silently mutate
  a marked row); unmark stays the escape hatch. pg test added.
- pass the active locale to getErrorMessage in the orders page and
  MarkOrderBookedDialog (CodeRabbit: English users got Swedish errors).
