feat: render Zapstore app curation sets (kind 30267)

- AppCurationSetEvent reads the `name` tag Zapstore uses instead of
  NIP-51's `title` (titleOrName, also used for NIP-50 indexing) and the
  NIP-82 `f` platform tags (platforms()).
- The set card shows the name and platform chips, and lists each kind
  32267 app as a compact row (icon, name, summary) that opens the app
  detail screen, instead of a full app card with screenshots per member.
  Rows show the app id until the app event loads.
- ListCard gains an optional subtitle slot.
