embedded3 S2-7b instruments: the quadratic / full-cells-only pressure probe (Mask::pressure_at_quadratic[_from]) and the DFG 2D-1 test's RTX_E3_DFG_DP_PROBE line; the manufactured sphere's pressure-error read by cell class + six signed wall-point reads, RTX_E3_MMS_SCHEME=tvd, the cut_cell_pressure_ladder and sphere_operator_probe tests (defaults untouched; MMS gates green)
