- Deleted outdated backend test cases (`test_auth.py`, `test_rate_limiting.py`, `test_users.py`) to clean up deprecated test structure.
- These tests are now redundant with newer async test implementations and improved coverage.
- Refactored all `password reset` and `auth dependency` tests to utilize async patterns for compatibility with async database sessions.
- Enhanced test fixtures with `pytest-asyncio` to support asynchronous database operations.
- Improved user handling with async context management for `test_user` and `async_mock_user`.
- Introduced `await` syntax for route calls, token generation, and database transactions in test cases.
- Implemented comprehensive tests for user management API endpoints, including edge cases, error handling, and permission validations.
- Added CRUD tests focusing on exception handling in database operations, soft delete, and update scenarios.
- Introduced custom `.coveragerc` for enhanced coverage tracking and exclusions.
- Improved test reliability by mocking rate-limiting configurations and various database errors.
