- Updated `verify_password` and `get_password_hash` to their async counterparts to prevent event loop blocking.
- Replaced N+1 query patterns in `admin.py` and `session_async.py` with optimized bulk operations for improved performance.
- Enhanced `user_async.py` with bulk update and soft delete methods for efficient user management.
- Added eager loading support in CRUD operations to prevent N+1 query issues.
- Updated test cases with stronger password examples for better security representation.
- Deleted outdated backend test cases (`test_auth.py`, `test_rate_limiting.py`, `test_users.py`) to clean up deprecated test structure.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.
- Introduced unit tests for `EmailService` covering `ConsoleEmailBackend` and `SMTPEmailBackend`.
- Added tests for password reset request and confirmation endpoints, including edge cases and error handling.
- Implemented soft delete CRUD tests to validate `deleted_at` behavior and data exclusion in queries.
- Enhanced API tests for email functionality and user management workflows.
