Implement complete bookmark functionality for Bible reading

Add both chapter-level and verse-level bookmarking capabilities:

Database Changes:
- Add ChapterBookmark table for chapter-level bookmarks
- Update schema with proper relationships to User and BibleBook models
- Maintain existing Bookmark table for verse-level bookmarks

API Endpoints:
- /api/bookmarks/chapter (GET, POST, DELETE) with check endpoint
- /api/bookmarks/verse (GET, POST, DELETE) with check and bulk-check endpoints
- JWT authentication required for all bookmark operations
- Multilingual error messages (Romanian/English)

Frontend Implementation:
- Chapter bookmark button in Bible page header with visual state feedback
- Individual verse bookmark icons with hover-to-reveal UI
- Highlighted background for bookmarked verses
- Efficient bulk checking for verse bookmarks per chapter
- Real-time UI updates without page refresh
