CI's "Apply database migrations" failed with asyncpg
UnsafeNewEnumValueUsageError: alembic runs the whole upgrade in a single
transaction, so migration 039's INSERT used 'grok' in the same transaction
that 038 added it — which Postgres forbids. Splitting into two migration
files did not help (one transaction spans both). Wrap the ALTER TYPE ADD
VALUE in op.get_context().autocommit_block() so the value commits before 039
(and any later migration) uses it. Still renders in offline --sql, so the
enum-migration-parity test is unaffected.
