feat(physics): A6.P1 — instrument AdjustSphereToPlane with [push-back]

Browse source 
Wires the LogPushBackAdjust helper into all three return paths
of AdjustSphereToPlane (early-return on no-movement, early-return
on interp out-of-window, and the applied path). Probe is gated by
ProbePushBackEnabled so it's zero-cost when off.
