Dashboard Studio 1.10.0: phone dashboards, room card, changelog

- Phone dashboards: a 4-column layout designed at phone width, with
  conversion both ways; on phones the top bar is hidden and comes back
  with a touch-and-hold on an empty spot
- Room card built from Home Assistant areas (area, device and entity
  registries): climate, lights on with an all-lights toggle, thermostat,
  open doors and windows, motion, media, and device buttons
- CHANGELOG.md for Home Assistant's Changelog tab, served at
  /api/changelog and shown under About > What's new
