fix(review): stage objects by their measured bounds, and aim the vehicle cameras at the car

The review notes named the same class of problem in six rows: things sitting a little too low or too
high in the floor. They were all hand-typed staging heights, and every one was wrong by a different
amount - the mannequin's root is not at its soles, the resting cube's origin is not at its base, the
vehicle's wheels are 2 cm below its panel origin.

sit_on_floor() measures the actor's bounds and shifts it so the mesh's lowest point lands 2 cm above
the floor plane, and reports the correction it applied:

  MPFB character    +2.0 cm
  ScaleTest_A      -48.0 cm   (it was floating)
  vehicle wheels    +2.0 cm

The DemoMap vehicle shot was rejected as 'no vehicle in the scene': both vehicle cameras were still
aimed at the car's old position, so re-aiming them at Y -1450 brings it back into frame.

Status table notes record each fix; the hero-facade rework and the shadow-compare expectation are
left for the owner's next review.
