zwitschi 021aa56121 test(vehicle): the pawn is the culprit, the meshes are fine ...

Decisive experiment: the same SM_Vehicle_Body staged as a plain StaticMeshActor 5.5 m
from the pawn renders, while the panels attached to the vehicle pawn do not - with
visible=1, the right mesh name, a 238 cm extent, MarkRenderStateDirty() and
UpdateBounds() all in place. The asset and its material are fine; the pawn's component
hierarchy is what keeps them out of the renderer.

So the car is now staged as nine plain StaticMeshActors (body, glass, front/rear lights,
mirrors, four wheels) alongside the physics pawn: visible, and not yet attached to the
driving pawn. A visible car that does not drive yet beats an invisible one that does.

Two defects found by the tools while chasing this, both fixed: the demo builder staged the
vehicle twice per run (the scene audit caught the duplicate label), and clear() could leave
actors behind, so it now repeats until nothing is removed.
