Add user profile management for smoking data

- Introduced new API endpoints `GET /api/v1/smoke/profile` and `PUT /api/v1/smoke/profile` for retrieving and updating user smoking profiles.
- Added a new database table `fa_smoke_user_profile` to store user-specific smoking data, including daily smoking habits and motivations.
- Updated the smoke handler and service to integrate user profile data into AI advice generation.
- Enhanced documentation to reflect the new user profile features and their usage.
