- per-airport ATIS loop keyed by station with a virtual start epoch, so
re-tuning resumes where the broadcast would be instead of restarting
- refetch airport data at :23/:53 to follow VATSIM ATIS regeneration from
real-world METAR publication, with faster retries while no ATIS is on
the feed; prefetch audio when the info letter changes
- support separate arrival/departure ATIS stations on different frequencies
- cancel the deferred audio teardown on retune so a fresh broadcast is not
killed by the previous stop()'s fade-out timer (atisAudioLoop)
- comm log shows newest entries first
