* island: open media and the power menu in one step, fix dash edits
- Clicking media on the home face opens the player. Closing a sheet
goes back to the face the user picked, and an opt-in setting
switches to media when playback starts.
- The power menu can open in the island (Super+X, the dock button),
with its own route row in the island settings.
- An island collapses when another popout opens on its screen.
- The widgets page hides the center section the island replaces.
- Dragging or resizing a dashboard card no longer blanks the overview:
Qt hands the committed list over as a non-array, which read as empty.
- The island blur region stays inside the rounded fill.
* fix(island): address review feedback on switching faces by mouse
Opening the player with one click removed the only mouse path from
the home face to the media face. A right-click on the collapsed island
now swaps between the two while media is available.
The swap resizes the island under the pointer, so hover-open stays off
until the pointer leaves. Without a face to swap to, the press is not
accepted and reaches the bar's own right-click action as before.
