Reset TC setpoints and stirrer to schedule on resume from pause

On resume from PAUSED, on_step_changed does not re-fire (same step
continues), so any manual TC/stirrer adjustments made while paused
would persist into the run. Explicitly re-apply the current step's
temperature, heatrate, and stirrer config on the resume path in
SudTask.recv().
