fix: update Civitai download row keys and LoraManager archive result keys

- Prefix rowKey with sourceKey in resolveDownloadMethods to prevent
  cross-source row collisions by using a composite identifier.
- Update LoraManager archive result check from 'url' to 'download_url'
  to match Civitai API response field naming, and fallback to model card
  URL using download_url to make the open button resilient when the
  direct URL is unavailable.
