Fix logo loading and URL parameter persistence

Backend:
- Added static file serving for /logos directory
- Logos now accessible at /logos/path for Docker builds

Frontend:
- Updated all navigation to include version parameters (?version=esv|?version=nkjv)
- Book selection includes version in URL
- Breadcrumb navigation preserves version context
- URLs now work for bookmarking and sharing with version information

Complete fix for both logo display and navigation URL persistence.
