feat(recipes): reconnect suggestions, undo, and base-model family tolerance

Enhance the deleted-LoRA reconnect flow in the recipe modal:

- Suggest local reconnect candidates when the panel opens, ranked by
  identity (same hash / same CivitAI version) then filename/name
  similarity, with a hard filter on confident base-model mismatches;
  the input gets a Combobox backed by the same endpoint as you type.
- Snapshot the pre-reconnect entry and offer a permanent restore:
  reconnected entries show an undo icon at the right end of the info
  row, with the original filename in the tooltip.
- Relax the manual reconnect base-model guard to a three-tier check:
  exact/unknown labels pass silently, same-architecture families
  (e.g. Pony <-> Illustrious) pass with a warning toast, and only
  cross-architecture mismatches stay hard-rejected.
