fix(import): request withMeta=true from CivitAI API, fix checkpoint type guard and CivArchive version lookup

- Add &withMeta=true to image info URL so API returns full generation
  metadata (resources with hash/type) instead of null meta
- Fix checkpoint assignment guard: check modelId instead of id so non-
  checkpoint types (upscaler) are not wrongly set as recipe checkpoint
- Skip modelVersionIds loop when resources/civitaiResources already
  provided LoRAs, preventing hash-resolved duplicates
- Fix int/str type comparison in CivArchive get_model_version so
  version ID matching works correctly
