The _update_migration_state() method was using pg_conn.execute() which has
its own connection management. This could cause issues with transaction
handling when called at end of migration.
Changed to use explicit cursor with guaranteed commit:
- Use pg_conn.connection.cursor() to get a direct cursor
- Execute the INSERT ... ON CONFLICT query
- Explicitly call pg_conn.connection.commit()
- This matches the pattern used in other parts of the code
This ensures that final migration state (completed status, final counts)
are properly persisted to the database.
