Add AI price verification feature

Browse source 
When enabled, AI verifies every scraped price to ensure accuracy.
This catches issues like scraped "savings" amounts instead of actual prices.

- Add ai_verification_enabled column to users table
- Create verification prompt and functions for Anthropic, OpenAI, Ollama
- Integrate verification step into scraper after traditional scraping
- Add verification toggle to Settings page (separate from AI extraction)
- AI verification is independent of AI extraction fallback

Flow: Traditional scraping -> AI verification (if enabled) -> AI extraction fallback (if no price found)
