Add Library theme with user images + fix theme system

New Library Theme Feature:
- Added 'Library (Random)' option to theme dropdown
- Uses random images from user's linked directories
- Fresh random selection on each page load/theme change
- Displays 10 random images from personal collection on home screen

 Theme System Improvements:
- Updated applyTheme() to handle async library theme loading
- Added applyLibraryTheme() function with proper error handling
- Fixed CSS loading to skip image-based themes (library, hentai, etc.)
- Improved file path handling for Electron environment
- Added fallback to hentai theme when no library images found

 Enhanced Dropdown:
- Added BBC and feet themes with proper image mappings
- Added Library theme with folder icon
- All 6 theme options now fully functional

 Result: Personalized home screen using user's own image collection!
