feat: Add express-async-errors for improved error handling

- Integrated express-async-errors to automatically handle errors in async route handlers, enhancing the overall error management in the application.
- Updated app.ts to include the express-async-errors import for global error handling.
- Removed redundant logging statements in admin and user menu retrieval functions to streamline the code and improve readability.
- Adjusted logging levels from info to debug for less critical logs, ensuring that important information is logged appropriately without cluttering the logs.
