Automated Action f9a4e68823 Fix Alembic configuration interpolation error
- Fixed configparser.InterpolationSyntaxError by simplifying alembic.ini format strings
- Updated env.py to handle configuration parsing errors gracefully
- Added proper exception handling for logging configuration
- Ensured database directory creation before migrations
- Added fallback engine creation if config parsing fails
- Simplified formatter configuration to avoid interpolation issues

The migration system now handles deployment environments more robustly.
