Follow up voice tilt review: superseded flights, wait, globe range

- A motion waiting on a voice fly-to follows a later fly-to in the
  same reply that cancels it, within one deadline, instead of
  reporting that its flight did not arrive. A stale reply stops
  following.
- The wait is 15 s, down from 30 s: it holds the tool output, and on
  Gemini the later tools in the turn.
- Beyond 1,000 km of range a tilt happens in place instead of
  swinging thousands of km about the crosshair point.
- The tilt-nudge limits read the pivot pitch the motion starts from,
  including for a voice tilt from a tracked view, whose follow camera
  is released before it moves.
- move_camera's argument checks run before the flight wait, so a
  malformed call is refused at once.
- Tests: t.after cleanup in the fly-then-motion loop, the pitchDeg
  pin asserts the field before removing it, and the handoff-order
  pin follows the extracted argument checks.
