feat: queue controls live only in the Queued view

Run/Remove selected/Clear list act on the queue, whose order only the
Queued chip view shows - in other views they are greyed out with a
tooltip pointing at the chip. Run stays enabled while automation runs
so pausing is always possible. Applies to the docked trio and the
pop-out clones alike.
