fix: use MeetingSpaceEvent.checkStatus() for nests feed thumb

NestsFeedLoaded.RenderLiveSpacesThumb gates LiveFlag/EndedFlag on
the kind-30312 status tag verbatim, so a host that crashed without
publishing a CLOSED replacement leaves the room flagged "live"
indefinitely. checkStatus() applies the same 8-hour age-out the
event's own helper uses, so abandoned OPEN rooms surface as
EndedFlag instead.

Also drop a stray println debug ("AABBCC …") in the same map block.
