Refactor handlers and OpenAPI documentation for improved readability and consistency
- Reorganized imports in health, notifications, social, thoughts, and users handlers for clarity.
- Updated function signatures in handlers to improve readability by aligning parameters.
- Enhanced JSON response formatting in notifications and thoughts handlers.
- Improved error handling in user-related functions.
- Refactored OpenAPI documentation to maintain consistent formatting and structure.
- Cleaned up unnecessary code and comments across various files.
- Ensured consistent use of `Arc` for shared state in AppState and WorkerHandlers.
