Enhance smoking tracking API with new features and improvements

- Added a new API endpoint `GET /api/v1/smoke/home` to consolidate core modules for the home dashboard, reducing the need for multiple requests.
- Updated the `smoke` routes to include the new home endpoint and improved user profile management with the addition of a `quit_date` field.
- Enhanced the algorithm for calculating daily targets and next smoke suggestions, ensuring accurate future time handling and user-specific recommendations.
- Improved API documentation to reflect new endpoints, response formats, and detailed field descriptions for better clarity and usability.
- Refactored user authentication handling in various handlers to streamline the process and ensure consistent error responses.
