feat(26-03): enhance PublicSetupCard with itemCount and creatorName

- Add optional itemCount and creatorName fields to PublicSetupCardProps
- Render item count badge (blue pill) when itemCount > 0
- Render creator attribution line when creatorName is present
- Reorder card layout: name, creator, then count/date row
- Add cursor-pointer to Link className
- Backward compatible: existing usages passing only id/name/createdAt unaffected
