Show a Planner question as waiting on a decision in chat

Running tools now read as a sentence-case activity, and only count
finished calls once there are some. A live ask call is waiting on
people, so it shows the decision icon, how many decisions it waits on,
and an Open button for the matching card instead of a spinner.
