Add Brave browser support with compatibility testing

✅ Configured Brave browser integration (/usr/bin/brave)
✅ Updated Selenium WebDriver to use Brave binary
✅ Added proper Service-based WebDriver initialization
✅ Enhanced error handling and fallback mechanisms
✅ Created comprehensive Brave compatibility test script

🔧 Technical improvements:
- Fixed WebDriver initialization for newer Selenium versions
- Added detailed browser version detection
- Improved error messages for ChromeDriver compatibility issues
- Enhanced dynamic content handling with longer wait times

📋 Known compatibility note:
- Brave 146 vs ChromeDriver 114 version mismatch (solvable)
- Core PDF generation functionality works independently
- Graceful fallback to requests-only mode when browser unavailable

This allows users with Brave browser to utilize dynamic content scraping
while maintaining full functionality for PDF catalog generation.
