Fix favicon not showing issue

- Use url_for() for all favicon and icon references in layout.html
- Add specific routes for favicon files to ensure proper serving
- Create dynamic webmanifest route with correct icon paths
- Import send_from_directory for serving static files
- This ensures favicons work correctly in all deployment scenarios
