ASOS re-scoring was upserting 458K records every 10 min while losing
the refractivity gradient (the key ducting indicator). HRRR hourly
provides all surface variables plus vertical profile data.
458K-record upsert held a connection for the entire transaction,
exceeding the 15s Postgrex timeout on prod. Set transaction timeout
to infinity and increase prod pool from 10 to 20.
- Add enqueue_for_qso/1 to directly enqueue weather/HRRR/terrain/IEMRE
jobs for a single user-submitted QSO (no cron, no bulk processing)
- Submit flow calls enqueue_for_qso instead of generic enqueue worker
- Add enrichment queues to prod config for on-demand processing
- Guard against HRRR fill values in store_hrrr_profiles (fixes badarith)
- Filter QSOs without pos2 in build_terrain_jobs
Only run live scoring (propagation, commercial, solar) in prod.
Backfill queues (weather, hrrr, iemre, terrain, enqueue) and the
QsoWeatherEnqueueWorker cron are dev-only for historical enrichment.
When a local .hgt tile is missing, download it from the public AWS S3
skadi bucket, decompress with zlib, and write to the tiles directory
before retrying the lookup. Falls back to Open-Meteo/OpenTopo APIs if
the download fails.
