test(vehicle): the writer is not in the pawn's tick

Browse Source

Sampled the actor transform immediately before and after Super::Tick on every frame: it never changes
there. The 'inside Super::Tick' line never fires, yet the actor climbs 400-1400 cm/s.

With the earlier results that leaves exactly one consistent candidate: the Chaos movement component's own
tick or its async physics step, outside APawn::Tick. That also explains why SetComponentTickEnabled(false)
did not stop the climb and why the body's reported velocity is ~0 while the actor moves - the movement
component is writing a transform it took from a vehicle state that was never created.

Next step is a subclass of UChaosWheeledVehicleMovementComponent that logs UpdateState /
OnUpdateTransform together with the vehicle-state pointer, so the write is caught at its source rather
than inferred from the actor.
