Custom Viz - Airspace Radar

**Airspace Radar** turns a table of aircraft positions into a live, animated radar scope inside Dashboard Studio — a rotating phosphor sweep, range rings, centre cross-hair, per-aircraft callsign labels and heading vectors. It's a striking way to present ADS-B / flight-tracking data, geospatial point movement, or any "things on a scope" dataset. The data contract is simple: **one row per aircraft**, with fields `hex`, `callsign`, `lat`, `lon`, `altitude_ft`, `heading`, `speed_kts`. Drive it from a live ADS-B feed (it pairs naturally with the companion **TA-airspace-watch** modular input that polls a tar1090/dump1090 receiver), from historical flight data, or from any search that produces those columns. Standard `studio_visualization` custom viz, theme-aware, dependency-free.
