feat: print number of runners and requests on "app runners"

Honestly would rather number them instead. I think that was requested before too.

Also requests are there temporarily, and this is really overloading the UI. Let me reconsider this, it is going to be harder to break this later.

Easy alternative is fal apps runners | wc -l

What is the purpose of the numbers? Eventually be able to target runners by number, e.g. kill runner X?

We can move the counts when we break things up

This is always inaccurate due to header, but also right now due to requests, it's quite difficult to make work
