- Introduced endpoints for user management, including CRUD operations, pagination, and password management. - Added new schema validations for user updates, password strength, pagination, and standardized error responses. - Integrated custom exception handling for a consistent API error experience. - Refined CORS settings: restricted methods and allowed headers, added header exposure, and preflight caching. - Optimized database: added indexes on `is_active` and `is_superuser` fields, updated column types, enforced constraints, and set defaults. - Updated `Dockerfile` to improve security by using a non-root user and adding a health check for the application. - Enhanced tests for database initialization, user operations, and exception handling to ensure better coverage.
