Fix missing Alembic down_revision

The migration declares down_revision as c9f1d2e3a4b5, but there is no corresponding revision file in alembic/versions, so the migration graph is disconnected and alembic upgrade head will fail to resolve this dependency. This blocks schema upgrades in any environment that runs migrations. Point down_revision at the current head revision (e.g., 5f4e2b0a6b8b) or add the missing revision.
