Improve Newegg scraper with better price and stock detection

- Add multiple price selectors for robustness
- Combine dollar/cents from price-current element
- Add JSON-LD fallback for price extraction
- Add explicit stock status detection for Newegg
- Prevents false out-of-stock detection from generic detector
