[Feature]: Ability to switch direction of horizontal scolling

### Pre-flight checklist

- [x] I searched existing issues and the [Roadmap](https://github.com/AprilNEA/OpenLogi#roadmap), and this isn't already tracked.

### Problem / motivation

I use MX Master 3 for Mac, and the horizontal scroll works inverse, and i'd like to see the option to change it's way.

### Proposed solution

Option to choose between natural and inverse directions

### Additional context

_No response_

Start by locating the GUI and button-action/remapping code that handles horizontal scrolling. Trace how scroll direction is currently selected, then add the natural/inverse choice described in the issue. Done means horizontal scrolling can be switched between both directions through the GUI and the selected behavior works with the MX Master 3.
