Refactor API integration and data fetching for genre, novel, and chapter pages

- Replace Prisma database calls with API fetches from the reader API in GenreDetailPage, GenresPage, SearchPage, ChapterReaderPage, and NovelDetailPage.
- Introduce new utility functions for API requests in server-api.ts, including error handling.
- Update authentication flow in auth.ts to sync Google login with the reader API.
- Modify NextAuth session and JWT types to include additional user information.
- Clean up unused imports and code related to Prisma and MongoDB connections.
- Adjust the configuration in next.config.mjs to remove unnecessary API routes.
