Subject: Add IDR713 radar fetch and APNG loop

radarFetch.sh fetches BOM IDR713 transparencies (24h cache) and the
last six 6-minute echo frames, composites them via cached lower/upper
plates, and publishes an APNG loop to /srv/www/radar/.

systemd: radar.{service,timer} on a 6-min cadence, with retry units
mirroring the synoptic pattern.

nginx: new radar.pestrel.com vhost (still commented in setup.sh until
DNS propagation is confirmed).

setup.sh provisions radar dirs, installs radar units, enables timer.
deploy.sh accepts synoptic|radar arg.

Parameterised on product code; adding another radar is a one-line
config change.

Spec: doc/bom-radar-spec.md.
