ADFA-4879: overlay header shows region size + keep the bar visible when minimized

- Header now reads: Downloading "name"  ·  <size on disk> (from the estimate), with a
  middle-dot separator; percent + speed stay on the line below.
- Minimizing (Hide) now keeps the title and the advancing progress bar visible and only
  hides the percent/cancel row, so you still see progress while collapsed.
