fix(dash): resolve pointer cursor hover issue in connected mode (#2845)

* fix(dash): cursor not changing to pointer in Connected Mode (#2831)

Replaces the full-screen background dismissal MouseArea in
DankPopoutConnected.qml with four edge strips that exclude
the popup body. The full-screen MouseArea at z:-1 was
suppressing child cursorShape propagation on Wayland when
combined with the full-screen input mask.

Blame: the connected popout architecture itself (the issue
does not repro in Separate Mode where background dismissal
lives in a separate PanelWindow).

* fix(dash): resolve pointer cursor hover issue in connected mode
