P6b: a new CalibrationBridge owns every calibration call and publishes
a `calibration` telemetry group (IMU per-unit and per-side progress,
gravity centre, lens, sensor cleaning, RC calibration state and live
sticks). Guided full-screen wizards cover compass, IMU, remote
controller, gimbal auto calibration, lens, sensor cleaning, centre of
gravity, propellers and a vision-sensor guide; gimbal adjust is a
horizon-line overlay on the live video. Every start goes through
SafetyGate.runMaintenance, and closing mid-run stops what the SDK can
stop.
Reachable from Settings > Safety > Calibration & maintenance, the
Aircraft Status calibrate buttons and the gimbal sheet. Not yet run on
an aircraft; the RC key sequence still needs checking per remote.
