WebP Express CloudHost.es Fix v0.25.9-cloudhost

✅ Fixed bulk conversion getting stuck on missing files
✅ Added robust error handling and timeout protection
✅ Improved JavaScript response parsing
✅ Added file existence validation
✅ Fixed missing PHP class imports
✅ Added comprehensive try-catch error recovery

🔧 Key fixes:
- File existence checks before conversion attempts
- 30-second timeout protection per file
- Graceful handling of 500 errors and JSON parsing issues
- Automatic continuation to next file on failures
- Cache busting for JavaScript updates

🎯 Result: Bulk conversion now completes successfully even with missing files
