Fixes #45668

Given the orientation of Left and Right views, I guess it makes sense for Front and Back to be swapped yeah.

Works well for a character set up this way to face forward (Z-):

So this does appear to be technically correct, but it's the opposite of how blender behaves. I guess blender is technically wrong, since "front" views the back. My expectation is that hitting 1 on the numpad will result in X being to the right. I wonder if we keep the correct naming but swap the key binds so that numpad 1 becomes the rear view?
