feat(transactions): steer private marking in locked periods to ignore, with v1 and MCP ignore verbs (#1661) (#2031)

Decision (option a): a private marking stays a real booking (eget uttag/insattning), so it remains blocked in a locked or closed period; the legal escape for rows that are not affarshandelser is ignore. Private + locked now returns TX_CATEGORIZE_PRIVATE_PERIOD_LOCKED with remediation naming the ignore paths instead of a bare PERIOD_LOCKED, on all four categorize surfaces and the bulk driver. New v1 POST/DELETE /transactions/{id}/ignore (isTransactionBooked-based 409, idempotent) and a staged MCP gnubok_ignore_transaction (+ accounted_ alias, search visibility to respect the tools/list payload ceiling) with operation_type ignore_transaction; the CHECK pair 20260831070000/070001 rebuilds the constraint from main's newest list plus the new value. Dashboard toast gains an Ignorera i stallet action. Closes #1661
