[2.0.13] (Steam Deck) UX Locomotive menu controls not consistent with map view

[Sora5487863]

This is about a steam deck control inconsistency that has been kind of annoying.

When riding in a locomotive, the map menu can be used to add both temporary and permanent stops to the schedule.

The map is panned with the left stick.
The cursor is moved with the right stick/left trackpad/right trackpad.

When clicking on a locomotive (from map or while riding) and being presented with the map and left hand GUI labeled "Locomotive" containing the train schedule, this behavior is different. As this is the only way to add temporary/permanent stops with the L2/R2+A shortcuts remotely, I believe it should be the same. In this mode the behavior is

The map is panned with the right stick.
The cursor is moved with the left stick/left trackpad/right trackpad.

This is an annoying inconsistency I had to add. It's similar to the previous behavior before the train GUI was changed to be full screen.

Left stick is used to navigate GUIs. So when opening the locomotive GUI, it should behave the same way, otherwise it would be an even more annoying inconsistency.
