feat: add radiosonde weather balloon tracking mode

Integrate radiosonde_auto_rx for automatic weather balloon detection and
decoding on 400-406 MHz. Includes UDP telemetry parsing, Leaflet map with
altitude-colored markers and trajectory tracks, SDR device registry
integration, setup script installation, and Docker support.
