feat(recipes): add reconnect remediation paths for missing recipe LoRAs

- Snapshot pre-rematch entry state (reconnectSnapshot) so rematched
  entries can be undone via the existing restore flow
- Bulk missing-LoRA downloads mark unresolvable failures hash-invalid,
  flipping those entries from download to reconnect candidacy
- Recipe modal always offers a reconnect action next to download for
  missing LoRA entries
- Rematch runs collect an opt-in relaxed-matching choice (also reconnect
  missing models by file name) via a pre-run options dialog on the
  global, bulk and single-recipe entries
- L4 (filename-level) matches are listed in a results dialog with
  per-entry undo
