The disable grid hotkey should allow the snap scale to be completely determined by the snapSize and world scale. This prevents snapRange from overriding in the case where grid is disabled. Additionally, we disallow grid snapping when the grid scale is not visible. This means that when zoomed out sufficiently to not show the minor ticks, these minor ticks will not override a snap Fixes https://gitlab.com/kicad/code/kicad/issues/12303
