Now resets both X and Y work coordinates with G92 X0 Y0 to prevent
coordinate accumulation on both axes.

     This keeps coordinates bounded and prevents soft limit errors.
     The soft limits check against MPos (machine position), which doesn't
     change with G92, so this is safe for the hardware.
