Dashboard Studio 2.3.0: light, light group and room cards redesigned

- Light card: the card is the lamp; brightness fills it in the lamp's colour,
  drag anywhere to dim, large brightness figure, switch and colour row
- Light groups: the group fader on top, a fader row per lamp in its colour
- Room card: name with what's going on, all-lights switch, large climate
  figures, open doors in amber, device tiles that glow by brightness
- Room: new "Hide these entities" field
