Make bolus-in-progress card in Treatments view more reliable

Some manual boluses left a bolusing card stuck at 0% in the Treatments
view that blocked further boluses and could not be dismissed until the
app was restarted (#1308).

The card was gated on bolusStatus, which mirrors the pump's reported
bolusState and can stay at inProgress after delivery has finished. Since
bolusTrigger now retains that value, the card resurfaced once a new
amount was entered, and the X could not clear it because there was no
active bolus to cancel.

Gate the card on bolusProgress instead, the local dose reporter signal
that clears reliably and that the Home view already uses, keeping the
initiating state so the pre-delivery view still shows.
