fix: verify returned image ID matches requested ID in CivitAI API

Fix issue #870 where importing recipes from CivitAI image URLs would
return the wrong image when the API response did not contain the
requested image ID.

The get_image_info() method now:
- Iterates through all returned items to find matching ID
- Returns None when no match is found and logs warning with returned IDs
- Handles invalid (non-numeric) ID formats

New test cases:
- test_get_image_info_returns_matching_item
- test_get_image_info_returns_none_when_id_mismatch
- test_get_image_info_handles_invalid_id
