Wire ADS-B end to end: secondary-sdr container running dump1090

node-26#9. New secondary-sdr-container claims the node's SECOND physical SDR (RTL-SDR index 1 — op25 always claims index 0; no serial-based binding yet, same gap op25 itself has). Its control API (start/stop/status/data, mirroring op25_controller.py) launches dump1090 in adsb mode and exposes the decoded aircraft.json snapshot; AIS mode 400s until it's wired next. edge-node: on_config_push starts/stops it when secondary_sdr_mode changes, lifespan resumes it after a restart if already configured, and a new telemetry_uplink_loop polls its /secondary/data every 10s and POSTs non-empty snapshots to C2's new /telemetry/adsb (same bearer-key pattern call_recorder.py already uses for audio upload). UNVERIFIED: this container has not been built or run against real hardware in this session (sandboxed authoring machine, no docker) — dump1090's --write-json field names are believed correct from its docs but not confirmed against a real capture. Build + hardware smoke test before this reaches a real node. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
