CivitAI image API returns modelVersionIds at the root level of the
response (not inside meta), containing ALL model version IDs across
all resources (checkpoint + LoRAs). Two bugs prevented LoRAs from
being discovered:
1. _download_remote_media only extracted the first modelVersionId for
enrichment, dropping the rest.
2. CivitAI API meta parsing only ran as an EXIF fallback, but most
images have embedded EXIF metadata (prompt, steps, etc.), so the
fallback was never triggered.
3. When civitai_meta_raw itself has a nested 'meta' key, unwrapping
it stripped the injected modelVersionIds.
Also fixed gen_params merge: API gen_params now overlays EXIF at the
field level instead of full replacement, preserving EXIF-only fields
like detailed generation parameters.
