island: open the window source's properties from the pill

A Wayland window capture is chosen in the portal picker, which only OBS's
source dialog can open. In a scene whose only source is a PipeWire capture,
the panel gets a Window button that opens that dialog. A window scene with
more than one source needs a per-scene designation the pill does not have yet.
