refactor: use Server Actions for read progress updates

- Create src/app/actions/read-progress.ts with updateReadProgress and deleteReadProgress
- Update mark-as-read-button and mark-as-unread-button to use Server Actions
- Update usePageNavigation hook to use Server Action
- Use revalidateTag with 'min' profile for cache invalidation
