feat: faster screensharing, one-click

[konsalex]

Lets make the sharing an one-click operation, when clicking it will select the display you opened Hopp in, and then the drop-down will help you change screens, with an extra option to open Display Picker maybe?

One question here is around quality of the stream, which maybe can also be part of the dropdown if needed.

• We need a faster overlay (not sure if this is tracked cc @iparaskev)

We can delay this until we make the quality dynamic (or selectable by the controller). Then we won't have to make the experience ugly.
