Fixes #2354 Root cause (tray freeze): In clickThrough mode, the PanelWindow mask uses sectionRect() with mapToItem() to compute input regions. After DPMS resume, the PanelWindow is recreated with width=0, and mapToItem() returns wrong positions. The right section's implicitWidth doesn't change after creation (fixed-size tray icons), so the mask binding is never re-evaluated when the compositor sets the actual screen width. Adding barWindow.width as a binding dependency ensures the mask recalculates on resize. Root cause (wallpaper loss): Wallpaper PanelWindows are recreated by Variants during screen reconnection before the compositor finishes output initialization. The wallpaper Image renders at 0x0 dimensions, resulting in a black screen. Changes: - DankBarWindow: add barWindow.width dependency to clickThrough mask bindings - DMSShell: add surface recovery mechanism (screen reconnect + session resume) with progressive 2-pass timer (800ms + 2800ms) that recreates bar, Frame, wallpaper, and dock surfaces after the compositor is ready - WlrOutputService: re-request output state on session resume
