feat: featured items — admin toggle, badge, sorted to top

- Add featured to ItemOverride so it can be set per-item in admin
- Catalog API applies the override and sorts featured items before
  non-featured (within each group, sortOrder still applies)
- ProductCard shows a teal Featured badge on the image when featured
  and not sold out
- Admin item editor has a ⭐ Featured checkbox beside Hidden
