docs(web): refresh demo-house screenshots + captions for colour & climate

Re-captured all 5 live HA dashboard views (consistent 1240px, no PII): overview
now shows the floor-heating climate snapshot, climate shows the 6 floor-heating
thermostats + valve gauges, lighting shows RGBW/RGB/CCT colour lights (the prior
'Ошибка' was a non-existent light-color tile feature, now removed). Site fact
cards + gallery captions + both READMEs updated to describe colour/climate.
