Add AI chat feature for verse explanations and fix login redirect handling

Bible Reader Enhancements:
- Add chat icon to each verse for AI explanations
- Implement handleVerseChat function with pre-filled contextual messages
- Chat opens with message: "Explain in depth this verse [text] from [version], [book] [chapter:verse] and its meaning"
- Visible to all users, redirects to login for unauthenticated users
- Fix copy message translation from 'bible.copied' to 'copied'

Login System Improvements:
- Fix redirect parameter handling in login pages
- Users are now properly redirected to /bible page after successful login
- Preserve redirect URL parameters through login flow
- Add Suspense boundaries for useSearchParams compliance
- Ensure verse/chapter context is maintained after login

Technical Changes:
- Add Chat icon import from Material-UI
- Implement floating chat event dispatch system
- Fix Next.js 15 build warnings with proper Suspense wrapping
- Maintain existing UX patterns (visible to all, functional for authenticated users)
