feat: identify working LLM models and improve debugging

- Tested Gemini API and discovered API key has access to gemini-2.5-flash and gemini-2.0-flash (NOT 1.5)
- Verified Groq llama-3.3-70b-versatile works successfully for extraction
- Confirmed LLM extraction pipeline IS working: example.com returns proper JSON with Groq
- Added comprehensive debug logging to track model resolution through router and providers
- Fixed GoogleProvider 404 error handler to extract actual model name from request URL
- Clear Python cache before testing to ensure code changes are picked up

VERIFIED: AI-driven extraction works with Groq on simple sites
TODO: Debug why CSV/JSON output not appearing in final streaming response for complex sites
