Bug 512102

Platform:artix-openrc with hyprland
If I try to start kdeconnect-app with the env being
```
QT_STYLE_OVERRIDE=kvantum
QT_QPA_PLATFORMTHEME=qt6ct
QT_AUTO_SCREEN_SCALE_FACTOR=1
```
I am getting the following output:
```
QQmlApplicationEngine failed to load component
qrc:/qt/qml/org/kde/kdeconnect/app/Main.qml: module "kvantum" is not installed
Failed to load the app false
```
However If  I try to specify the style argument it starts with a default theme:
for instance:
`kdeconnect-app -style 1` 
I am getting the following output and app starts normally:
```
QApplication: invalid style override '1' passed, ignoring it.
	Available styles: kvantum-dark, kvantum, Windows, Fusion
kf.kirigami.platform: Failed to find a Kirigami platform plugin for style "org.hyprland.style"
qrc:/qt/qml/org/kde/kdeconnect/app/WelcomePage.qml:13:1: QML WelcomePage: Created graphical object was not placed in the graphics scene.
