[Bug]: Linux Desktop Client : window buttons require window resize to work

### Summary

When right click on icon, Show defguard client, the client appears but its window buttons (close, maximize, minimize) are not active.
Maximizing the window with keyboard shortcut make the buttons work again.

### Steps to reproduce

This is probably highly dependant on distribution / Desktop, and other details, so here is my setup
- popOs 24.04
- Gnome 46
- Wayland

0. Login to user session
1. Start defguard client
2. it opens, window buttons have no effect, hover them or click them does nothing
3. right click in systray icon to Hide the window works
4. when visible, use mouse movement or keyboard shortcut to maximize the window
5. then hover the buttons : they work again.

### Expected behavior

Window buttons should work as soon as window is displayed

Inizia riproducendo il problema su PopOS 24.04 con Gnome 46 e Wayland, usando l’azione del clic destro nella system tray “Show defguard client.”. Traccia il percorso di presentazione della finestra e verifica che chiusura, massimizzazione e minimizzazione rispondano immediatamente dopo la comparsa della finestra, senza richiedere un ridimensionamento tramite tastiera o mouse.
