+-- Tear out the hand-rolled `audit_log` domain-history table and realign the
+-- framework `audit` sink to the canonical pikku AuditEvent shape (audit_id PK,
+-- actor_user_id, data JSON). Domain row-change history now flows through the
+-- pikku audit service — KyselyAuditService locally, a platform queue sink in
+-- prod — persisted here and read back by get-booking-audit-log via metadata →
+-- data. The old `audit` table had a drifted shape and was never written to.
