Add inline queue progress bar and text summary (#8271)

Add inline queue progress bar and summary per the new designs.

This adds an inline 3px progress bar in the actionbar container (docked
or floating) and a compact summary line below the top menu that follows
when floating, both gated by the QPO V2 flag and hidden while the
overlay is expanded.
