window-curvature, frame-controls: a curvature drag cancels the long press after the ring too

When the ring shows, frame-controls no longer takes the press over via
cancelPress(); it raises the press's drag threshold to 3x via the new
window.__sfuiWindowCurvature.scalePressDragThreshold(factor) (measured from
the press start). Laser drift keeps the long press, a deliberate drag starts
the curvature drag and cancels it. Completion still calls cancelPress().
