Fix: Preserve direction-change commands when stopping motors

Use stopAllMotors() instead of stopAllMotorsNow() to avoid clearing the
command queue. This ensures direction-change and SAVE_SETTINGS commands
complete even when spacebar is released or dialog is closed.

stopAllMotorsNow() retains its original behavior (clears queue) for
emergency stop scenarios where immediate halt is required.
