revert(db): remove Alembic migration system
Remove Alembic database migration system in favor of delta scripts:
Deleted:
- runtime/datamate-python/alembic.ini (config file)
- runtime/datamate-python/alembic/env.py (environment config)
- runtime/datamate-python/alembic/script.py.mako (migration template)
- runtime/datamate-python/alembic/versions/20250205_0001_add_file_version.py (migration)
Modified:
- scripts/db/data-annotation-init.sql
- Removed alembic_version table creation and version insertion
- Kept file_version column in t_dm_annotation_results
Rationale:
- Alembic migration testing failed in production
- Delta scripts are simpler and more reliable for this project
- SQL init scripts contain complete schema including latest changes
