fix(launches): hand the camera over before stopping, and only blame a fresh index error

- releaseCameraOwnership marks the camera released before stopping, so a
  flight navigation asked to preserve survives; exit also releases it, so an
  inactive layer never cancels another owner's flight.
- The failure toast names the mission index only when its error is from the
  current Context attempt (stats.errorAt), not an earlier one.
