test(vehicle): the body barely moves, so something else moves the actor

Browse Source

The motion probe splits the problem in two:

  velocity  -24, -182, -28 cm/s     (a body that cannot climb 9 m in 1.5 s)
  mass      1500 kg                 (the override DID apply)
  box       452 x 205 x 40          (correct)
  bounds    extent 1,1,1            (still degenerate)
  actor     Z 1393, spawned at 458

The physics body is nearly still while the actor is nine metres above its spawn. So this is not a
force problem at all - it is a transform problem: something writes the actor's transform that is
neither the body's velocity nor our code, which is also what the degenerate bounds are telling us from
the other side.

Next: find who writes that transform. Suspects are the Chaos movement component's UpdateState /
OnUpdateTransform and the component hierarchy - a pawn whose root is the mesh while the physics state
belongs elsewhere behaves exactly like this.

Pawn parked again so the demo stays clean.
