- Introduced `docker-compose.deploy.yml` for deployment scenarios with pre-built Docker images. - Added `auth_test_utils.py` to simplify authentication testing in FastAPI. - Implemented `security.py` for token-based operations like file uploads and password resets. - Created `init_db.py` for database initialization and superuser creation during startup. - Updated dependencies and tests to support optional authentication in FastAPI. - Enhanced entrypoint script to handle database initialization.
