feat v1.27.0: RGB light colors + red alarm pulse (issue #3)

- lightColorOf(): on+rgb_color tints icon/glow/ripple (explicit ripple color wins);
  brightness ignored by design; off/white/unavailable unchanged
- isAlarmState(): leak/smoke/gas/CO/safety/tamper/problem sensors and sirens in
  'on' pulse a red ring over any display mode; outages never alarm;
  prefers-reduced-motion honoured
- +2 unit tests, smoke_rgb_alarm.mjs, TESTING.md rows
