Fix Preferences dialog sizing on multi monitor setups

[Ocraftyone]

Description

Update the way the preferences dialog size is set. Currently, on multi monitor setups, only the resolution of the main display is used, even if the window is on a different monitor with a different resolution. Now, the resolution of the monitor displaying the window is used in the sizing calculation. Also, rather than getting the total vertical resolution of the monitor, it gets the usable (or as wxWidgets calls it, the client resolution). This gets the area of the screen that does not include the task bar.

Why is the preferences a floating window instead its own tab/ui?

[Ocraftyone]

The main reason is probably because that is how PrusaSlicer and Bambu Studio have done it and there is not really a reason to change it. Why would you want to make it a page/tab though? These settings are typically not adjusted that often, so making it a tab would just be more clutter on the top bar with little benefit.

[Jaizu]

Because having a popup window for no reason is just ugly and annoying, doesnt cover the entire screen and its a big list. Using the entire ui would allow for better organization and less scrolling.
Super very quick and ugly mockup

Currently, adding settings to a big thin list makes it like a nightmare, having the size of your screen organized is a much better ux approach, is not like you want/need to see the bg of the UI while you are in preferences.

[ElectricalBoy]

I don't really disagree with @Jaizu's idea, but I think it should be a separate FR.

[Ocraftyone]

Personally, I think having it's own window is the right choice. I understand that scrolling is not ideal, but I think that should be managed with tabs like PrusaSlicer does. Having a giant wall of text I feel would be very overwhelming.

Good one!

Displaying preferences in a modal dialog is a standard approach in desktop applications.
Showing them in a tab also makes it a bit odd from a UI/UX perspective(in the context of Orca).
All tabs in Orca are for printing-related settings and are organized with that logic, whereas software preferences are different—they are about the software itself, not the actual printing-related settings.
