fix: resolve critical MVP issues - search bar overlap and language selection

- Fix search bar covering main menu: removed fixed positioning from header and use flex layout instead
- Fix Bible not displaying in selected language: pass locale parameter to /api/bible/books endpoint
- Add locale dependency to loadBooks useEffect so Bible content updates when language changes

These fixes make the MVP fully usable for all languages (en, ro, es, it).
