- Refactored `create_user` and `change_password` methods to add transaction rollback on failures and enhanced logging for error contexts.
- Updated security utilities to use constant-time comparison (`hmac.compare_digest`) to mitigate timing attacks.
- Adjusted API responses in registration and password reset flows for better security and user experience.
- Added session invalidation after password resets to enhance account security.
- Migrated database sessions and operations to `AsyncSession` for full async support.
- Updated all service methods and dependencies (`get_db` to `get_async_db`) to support async logic.
- Refactored admin, user, organization, session-related CRUD methods, and routes with await syntax.
- Improved consistency and performance with async SQLAlchemy patterns.
- Enhanced logging and error handling for async context.
This commit introduces a suite of tests for user models, schemas, CRUD operations, and authentication services. It also adds utilities for in-memory database setup to support these tests and updates environment settings for consistency.
