feat v1.44.0: control-first device card + light-source flag (user feedback)

- device card opens with controllable entities: toggles inline (finger
  targets), cover/lock/climate hand off to HA more-info; metadata and
  manuals moved below; config/diagnostic entities filtered; locks still
  never toggle from a card
- marker.is_light: a smart switch driving dumb fixtures glows in the
  light-sources fill (its own entity or the bound controls) — no
  light-group helper needed
- backend schema; smoke_card_controls.mjs, smoke_glow extended; docs
