[Desktop] Add support for previous and next keyboard shortcuts/mouse buttons

[mathieures]

Summary

Hello, I discovered Fladder only a couple of days ago and I already find it great! I downloaded the Windows portable version to try it out without installing anything, and it’s super nice to have the option to do so.

After exploring a little however, I was surprised that clicking on the "previous" button on my mouse had no effect, instead of taking me back to the page I was on previously, like in a web browser or file explorer for example. I think it would be a nice addition to navigate the app more easily (I believe it is the same as hitting Alt+Left/Right arrow on the keyboard, which doesn’t do anything either).

Would it be possible to implement this feature for the desktop version?
Thank you for the cool project and thank you for your time!

My environment: Windows 11, Fladder version 0.6.1, build 137

Basic Example

1. When clicking on the "previous" button on a mouse or hitting Alt+Left Arrow on a keyboard, if there is a page in the history, go back to this previous page
2. When clicking on the "next" button on a mouse or hitting Alt+Right Arrow on a keyboard, if we already went back one or more pages, go to the next page in the history

Drawbacks

There may be an issue porting this feature to other platforms, as there are no mouse or keyboard on a TV or a smartphone. I don’t know the code at all, so I can’t really say how hard it would be to implement this.
