Replays sha256 chain in given audit partition from given id:
1. Uses pgsql_supplier (BYPASSRLS) to see all rows regardless of RLS scope.
2. Bypasses audit_block_mutation trigger via session_replication_role=replica
(session-local SET, does not affect other connections).
3. Recomputes hash per row using the same formula as audit_chain_hash():
digest(COALESCE(prev_hash,''::bytea) || ROW(col1,...,NULL::bytea,...,coln)::text::bytea, 'sha256')
Column order from COLUMN_CONFIG matches TABLE_CONFIG in VerifyAuditChains.
4. Supports --dry-run (count without UPDATE) and --force (skip confirmation).
Validated against breaking partitions:
--partition=activity_log_y2026_m05 --from-id=599
--partition=balance_transactions_y2026_m05 --from-id=462
Tests: 4 tests — activity_log rebuild, balance_transactions rebuild,
dry-run no-op, unknown partition rejection. All pass (4/4 GREEN).
