- Removed legacy Alembic migration files and consolidated schema management into a new Pydantic-backed initializer (`scripts/init_db.py`). - Updated `main.py` to ensure the new DB initializer runs on startup, maintaining idempotency. - Adjusted session management in `config/database.py` to prevent DetachedInstanceError. - Introduced new enums in `models/enums.py` for better organization and clarity. - Refactored various models to utilize the new enums, improving code maintainability. - Enhanced middleware to handle JSON validation more robustly, ensuring non-JSON requests do not trigger JSON errors. - Added tests for middleware and enums to ensure expected behavior and consistency. - Updated changelog to reflect significant changes and improvements.
