feat: implement SEO-friendly URLs for Bible reader

- Add dynamic route structure /[locale]/bible/[version]/[book]/[chapter]
- Convert UUID-based URLs to readable format (e.g., /en/bible/eng-kjv/genesis/1)
- Implement automatic redirects from old URLs to new SEO-friendly format
- Add SEO metadata generation with proper titles, descriptions, and OpenGraph tags
- Create API endpoint for URL conversion between formats
- Update navigation in search results, bookmarks, and internal links
- Fix PWA manifest icons to correct dimensions (192x192, 512x512)
- Resolve JavaScript parameter passing issues between server and client components
- Maintain backward compatibility with existing bookmark and search functionality

Benefits:
- Improved SEO with descriptive URLs
- Better user experience with readable URLs
- Enhanced social media sharing
- Maintained full backward compatibility
