fix: SQLite concurrency safety and atomic decision writes
Enable WAL + busy_timeout in _connect (ThreadingHTTPServer concurrent operators no longer hit 'database is locked'), add a _transaction helper and thread an optional conn through _put/_get/add_audit_event so record_decision commits its status change, watchlist entry, and audit event atomically.
