monolith: follow window geometry changes in the input space

Windows were mapped into the Space at their placed rect minus geometry().loc only during apply_layout, while drawing reads the geometry every frame. GTK sends its first buffer with shadow margins and drops them once configured as tiled, so caja was drawn at its rect but hit-tested a shadow width up and left until something re-laid out its output.
