20260316e: Fix quick recipe + use from opened packages first

- Quick recipe: prompt now specifies 1 persona, excludes freezer products
- USE form: auto-selects location with opened package as default
  (deducts from already-opened packages before sealed ones)
- Move-after-use modal verified working (shows after partial use)
