feat(ui): Make the downloads list scrollable

[LeoniePhiline]

You can only ever see as many downloads as fit your terminal. This can be an issue on pages with many embeds or on embedded showcases with many individual videos.

@kiri35 As a workaround, you can zoom out / reduce the terminal font size. This should also fix the "Finishe" label, which, as it sounds like, is cropped in your terminal due to insufficient column width. Smaller font size or larger terminal window should do the trick.

Thank you!
Zoom in/out (ctrl+/ctrl-) works for me, if i have less than 30 downloads :-)

The "Finishe/d" label is than visible.

No. It is for, if there are more downloads activ, than they fit in the terminal window, that is than not high enough.
