CLI export: disable the editor grid in rendered output

Browse Source 
renderDiagram() had a no-op stub: was_drawing_grid was set to false and
Q_UNUSED'd, so the editor grid still leaked into exported PDF/PNG/SVG.
Toggle Diagram::setDisplayGrid(false) around the render and restore the
previous state afterwards. Fixes all three export formats (they share
renderDiagram).
