feat(radar): log NEXRAD fetches + worker progress

Browse source 
Previously the CommonVolumeRadarWorker ran silently — no URL logged,
no sign in the logs that it was doing any work. Added info-level
fetch/ok/error logs in NexradClient (same shape as WeatherFetchWorker
RAOB logs) plus start-of-work + ingestion lines in the worker itself.
Unchanged: the existing "no frame" warning and all control flow.
