Fix step-1-skipped-on-restart race and Progress tab step number mismatch

Re-enabling the temp controller landed unconditionally in HOLD and
relied on the next tick to correct it, but SudTask.on_process() reads
is_holding() synchronously in the same call chain that pushes a fresh
step's setpoint - so a restart could finish a hold-less step instantly
instead of actually ramping. Resolve the FSM against the real gap right
away instead. Also fix the status bar showing one step number below
what the Progress tab's plates show for the same step.
