Dashboard Studio 1.7.0: scroll and swipe cards, more themes, per-device dashboards

- Container cards: horizontal scroll (snap, arrows, keeps position) and
  swipe (dots, optional autoplay that survives redraws and respects
  reduced motion), with add/edit/reorder of the cards inside
- Nine new themes, contrast-checked, including High contrast; bright
  accents get dark text
- Choose which dashboard opens per device (optionally in kiosk mode)
  and per Home Assistant user, via /api/whoami and the ingress user
  headers
