Enhance smoking tracking API and documentation

- Updated the main.go file to set the local time zone to Asia/Shanghai.
- Changed API endpoints from `PUT` to `POST` for user profile and logs management in multiple documentation files to reflect the correct usage.
- Added new fields in the API response for home summary, including `last_smoke_at`, `today_count`, `resisted_count`, and `reduced_from_yesterday`.
- Enhanced documentation across various files to accurately describe the updated API endpoints and their expected behaviors.
