fix: Correct proxy configuration for Crawl4AI compatibility

- Changed proxy format from dict to string (http://user:pass@ip:port)
- Updated get_random_proxy() to return Crawl4AI-compatible format
- Replaced deprecated 'proxy' with 'proxy_config' in BrowserConfig
- Fixed test script to handle new proxy format
- Added credential hiding in proxy logging for security

Fixes AttributeError: 'dict' object has no attribute 'strip'
