fix v1.44.5: room climate counts hidden sensors; drop the stale room tooltip

- areaClimate() walks the HA registry for the area instead of the list
  of VISIBLE icons: a thermometer hidden by curation or by the user was
  silently dropped from the room card, tooltip and temperature fill
  (field report). Curation still filters fridges/TRVs; the auto icon is
  used on purpose so a custom marker icon cannot change what a device
  measures; an explicit per-room source still wins
- room tooltip no longer says 'open the area' — room clicks were removed
  in v1.40.1 (the link icon does it)
- +1 unit test (120); both changelogs updated
