Publish segment end time for valid recording segment updates
The record watchdog compares latest_valid_segment_time against now() with the record_stale_threshold. Publishing the segment start time means the newest validated timestamp is already ~2x segment duration old in healthy steady state (own duration + next segment recording + maintainer latency), leaving little margin before a working ffmpeg record process is restarted. Publish the end time so staleness measures the actual age of the newest validated video data.
