[Enhancement] Don't override the QStyle to Fusion, and respect the DE's colour scheme.

[RokeJulianLockhart]

Errata (and Environment)

Currently, I have the "Breeze" QStyle set (via kcm_style):

Specifically, that includes:

1. #!/usr/bin/env sh
   rpm -qa | grep -i breeze

2. 1. breeze-icon-theme-6.11.0-1.fc41.noarch

   2. kf6-breeze-icons-6.11.0-1.fc41.x86_64

   3. breeze-gtk-common-6.3.1-1.fc41.noarch

   4. plasma-breeze-common-6.3.1-1.fc41.noarch

   5. plasma-breeze-qt6-6.3.1-1.fc41.x86_64

   6. plasma-breeze-qt5-6.3.1-1.fc41.x86_64

   7. plasma-breeze-6.3.1-1.fc41.x86_64

   8. qqc2-breeze-style-6.3.1-1.fc41.x86_64

   9. breeze-cursor-theme-6.3.1-1.fc41.noarch

   10. breeze-gtk-gtk4-6.3.1-1.fc41.noarch

   11. breeze-gtk-gtk3-6.3.1-1.fc41.noarch

   12. breeze-gtk-gtk2-6.3.1-1.fc41.noarch

However, I see the undermentioned in app/io.github.chidiwilliams.Buzz/x86_64/stable --commit 6070a19f9261c2317ae7acaedd02f0251aa87d8dd3dc6b2cbd72337389d0828f:

You'd think that the cause is flatpak-1.16.0-1.fc41.x86_64, but that's untrue:

1. #!/usr/bin/env sh
   flatpak override --show

2. [Context]
   filesystems=xdg-config/gtk-3.0:ro;xdg-config/gtkrc-2.0:ro;xdg-config/gtk-4.0:ro;xdg-config/gtkrc:ro;

@RokeJulianLockhart thanks for the issue report. I am not familiar with all the nuances of app styling and theming so some input and guidance would be welcome.

In the Buzz app we explicitly set styles for Windows in the Dark mode, I think everything else uses default styles as set in the OS.

Maybe some tips from this are needed to set the necessary styles https://wiki.archlinux.org/title/Uniform_look_for_Qt_and_GTK_applications

If you see some way Buzz app could improve this, please explain in a bit more detail what exactly would be needed or should be done.
