feat(scraper): wire orphaned anti-detection modules into fallback chain

- Integrate TLSScraper (curl_cffi TLS fingerprint impersonation) as Tier 2.
- Integrate CamoufoxBrowser as Tier 6 stealth Firefox alternative.
- Inject StealthEngine.generate_all() into Playwright contexts in both ultimate_scraper.py and scraper.py.
- Update UltimateScraper docstring to 12-tier fallback chain.
- Add 18 tests covering TLS, Camoufox, full fallthrough, and tier success paths.
- All 518 tests pass; ruff clean.
