Bohan Jiang 3ce25d16e7 fix(migrate): auto-backfill attribution before migration 198 to unblock self-host upgrade (MUL-4897) (#5558) ...

Self-hosted upgrades to v0.4.3 failed closed on migration 198's VALIDATE of the strict attribution constraint, because the legacy rows migration 190 exempted were only backfilled out-of-band on cloud. Registers a pre-198 preMigrationHook that idempotently mirrors originator_user_id into accountable_user_id in batches before VALIDATE, with FOR UPDATE + repeated predicate to avoid clobbering concurrently-written rows, so a stuck-at-197 instance auto-heals on migrate up with no manual SQL. Originator-NULL rows are left untouched. Verified with unit + concurrency + end-to-end tests against real Postgres.

Fixes #5544
