v1.44.6: room climate counts only air temperature

After v1.44.5 read the area registry instead of visible icons, every hidden
temperature entity in the area became a candidate, including ones measuring
something other than room air. Verified against a live 60-area install: a NAS
processor temperature, kettle water, a 90 C sauna heater and a virtual
better_thermostat all leaked into room averages.

- areaClimate(): skip entity_category (diagnostic/config), skip EXCLUDED_DOMAINS
  platforms, skip entity ids naming a non-air medium (water/coolant/flow_temp/
  return_temp/target/setpoint/chip/cpu/processor/board/device_temp/batter/
  freezer/fridge/oven/kettle/boiler).
- rules.ts: kettle/thermopot -> mdi:kettle, sauna/harvia -> mdi:hot-tub, so they
  no longer fall through to the generic thermometer rule.
- test: all four real false positives asserted out, one real sensor left.
- docs: CHANGELOG.md + CHANGELOG.ru.md + STATUS.md snapshot.
