Subject: [PATCH] Keep status bar visible in convergence mode

The status bar was hidden whenever a window was showing because
the fullscreen property evaluated autoHidePanelsEnabled without
checking convergence mode.  Return false from fullscreen when
convergence is active so the bar stays on screen.

Use WindowsGoBelow visibility mode in convergence so PanelView
does not manage the exclusive zone (it would fight with the
LayerOverlay layer set by QML).  Add a separate layer-shell
surface at LayerBottom with an exclusive zone matching the bar
height, following the same pattern as the dock space reserver.
Re-run setWindowProperties on convergence mode changes.
