/**
 * setTransactionIgnored (issue #1661): the shared core behind the dashboard
 * ignore route, the v1 ignore verb and the staged MCP ignore_transaction
 * executor.
 *
 * Pins the contract the three doors rely on: "already booked" is decided by
 * isTransactionBooked() across all three anchors (journal_entry_id, payment
 * allocations, voucher links), the flag flip is idempotent, restore skips the
 * booked check (the DB CHECK already guarantees an ignored row is unbooked),
 * dry run writes nothing, and DB failures throw with their SQLSTATE intact.
