fix(recipe): detect and repair corrupted checkpoints in repair flow

Browse Source 
Add corruption detection to _repair_single_recipe: if checkpoint.modelVersionId matches any LoRA's modelVersionId, the checkpoint is corrupted (a LoRA was saved as checkpoint). Clear the checkpoint and remove the matching LoRA entry, then let enrichment re-resolve the correct checkpoint from CivitAI metadata.

This fixes the retroactive repair path for the modelVersionIds[0] fallback bug.
