Allow Variable Optic Magnification to Be Changed While Not ADS

Currently, variable-magnification optics can only have their magnification changed while aiming down sights.

It would be great if we could also change the magnification while not ADS, using the same magnification-toggle key.

This would allow players to prepare the appropriate zoom level before aiming or entering an engagement. For example, if I'm moving from an indoor area into a long sightline, I could switch from 1x to 3x or 6x beforehand instead of having to ADS first just to change the magnification.

I don't think this would provide any meaningful balance advantage, since the player is simply selecting a magnification level that is already available on the optic. It would mainly make variable optics feel smoother and more intuitive to use.

I think this would be a small but very useful quality-of-life improvement for variable optics.
