Product detail: resources section layout 3 "Hardware option"

- The Resources Section Layout select gained a third value, hardware
  ("Layout 3 - Hardware option"): Technical Highlights spread over two
  columns, no resource cards
- ProductShowJsonRenderer::resourcesBand() emits the same envelope with
  items: [] for hardware even when cards are maintained, so the cards
  stay on the product and reappear when switching back to layout 1 or 2
- Spec v1.27 (resources.sectionLayout values)
