Diagnostic probe to discriminate two hypotheses for the Newton ~10x reward
gap on Shadow-Hand-Over MAPPO at the develop pin:

- If reward jumps sharply (e.g. mean from 27 -> 100+), the actuator wiring
  works and the baseline gains were just too low; sweep for sweet spot.
- If reward stays ~27, the wiring is broken (e.g. Newton issue isaac-sim#2585
  imports MjcActuators as CTRL_DIRECT, fixed in PR isaac-sim#2598 which is 51
  commits past our pin a27277ed). Switch to IdealPDActuatorCfg or bump
  Newton.

Will revert/replace this commit once the diagnostic is interpreted.
