Refactor API routes and remove unused endpoints

- Deleted the following API routes:
  - `upload-cover`
  - `truyen/[id]/chapters`
  - `truyen/[id]/comments`
  - `truyen/[id]/rate`
  - `truyen/suggest`
  - `user/bookmarks`
  - `user/recommendations`
  - `user/settings`

- Updated `chapter-client.tsx` and `novel-client.tsx` to handle error messages more gracefully.
- Adjusted pagination logic in `tim-kiem/page.tsx` to improve user experience.
- Added support for additional search parameters in the search functionality.
- Introduced API rewrites in `next.config.mjs` to route requests to a reader API.
