v1.52.0: one look for light sources, whatever flipped them

Owner's rule, agreed 2026-07-29 after a field report (a lamp turned off by
tap looked different from one turned off by the wall switch):

- a lamp's colour lives ONLY in its glow. The v1.27 RGB tint of the icon,
  border and shadow is deleted — that tint was the fork: with colour data
  the lamp rendered dark-with-coloured-icon, without it plain yellow, and
  the same lamp crossed the fork depending on how it was switched.
- in glow fill the indicator IS the spot: a source's badge stays standard,
  lit or not (litLightEntity — the exact condition that casts the spot —
  gates the suppression, so a lit socket keeps its yellow even in glow).
- in every other fill a lit source is plain yellow, like a heating TRV.
- icon morphing stays everywhere; the ripple colour still falls back to the
  light colour (both explicitly confirmed by the owner).

smoke_light_badges covers the whole table (8 assertions); smoke_rgb_alarm
re-asserted: no rgb class, lit lamp yellow, ripple fallback keeps the
colour. README colour language updated. Inventory: 147 / 51 / 43 / 70.
