Reset standing height and hip offset to stock defaults

Standing height was 0.72m (should be -1.0 = planner default 0.789m).
Hip pitch offset was 3.0 deg (should be 0.0 = no post-NN bias).
Both were experimental overrides that didn't fix knee straightening
and may have been causing subtle planner input mismatches.
