Direct controls on wide cards, weather/climate cards, spinner busy state (0.2.23)

App 0.2.23 / firmware 0.2.19.

- Wide cards of climate, switch, light, fan, vacuum, cover, media_player,
  number, select, timer, scene, script and button show Home Assistant style
  controls on the right (keys, -/+ pill with debounced send, slider with
  handle, toggle, run key); per-tile choice `options.controls` in the editor
  with mockup preview; the add-on sends only the set a card really shows.
- Weather card: now + next hours and coming days with rain, from daily and
  hourly forecasts; scenes/scripts/buttons show when they last ran.
- Climate card: power key, tap-to-toggle option, fan and swing rows in a
  redesigned mode picker (grey backdrop, white chips, accent selection).
- Busy state as a spinner on a translucent sheet; render guards so only
  changed styles reach LVGL; dark theme removed from the runtime code.
- supported_features above 1e6 reaches the screen; middle dot in text fonts;
  18 control glyphs in the icon fonts; diagnostics services
  preview_climate_picker and preview_busy; demo layout --controls.
