feat: Add scraper version selector to frontend

- Add version selector dropdown in scrape confirmation modal
- Default to v1.1.0 (Multi-Sort) which bypasses ~1000 review limit
- Pass scraper_version through API proxy to backend
- Update /new page fallback to show v1.1.0 as available
- Show version description explaining multi-sort benefits
