fix(recipes): resolve stale LoRA hash on import and add hashInvalid state

- import: prefer A1111 Lora hashes (12-char AutoV3) over conflicting Hashes
  JSON values; recover the quote-wrapped AutoV3 from CivitAI image API meta;
  merge EXIF-parsed LoRAs when the API-only parse yields none (meta=null)
- rematch: treat entries whose hash failed CivitAI resolution (hashInvalid)
  as unresolved candidates; clear the flag on rematch/reconnect write-back
- download: persist hashInvalid and show a distinct toast when hash lookup
  returns "Model not found", so unresolvable entries become recoverable
- ui: add Unresolvable Hash badge styling and reconnect affordance
- i18n: translate the new keys across all 10 locales
