fix: resolve rides API test failures and improve code quality

- Fix E2E live_server fixture (remove broken custom fixture)
- Fix Rides API factory mismatch (parks.Company → rides.Company)
- Fix duplicate block title in base.html template comment
- Fix test URLs for filter-metadata and search-ride-models endpoints
- Add fallback labels in SmartRideLoader to prevent ValueError
- Update test assertions to match actual API response structure

Rides API tests: 38/67 → 67/67 passing
