Remove close button when allow mouse is false

I have switched off "Mouse" in the settings, but the close button is still displayed without function:

<img width="516" height="275" alt="Image" src="https://github.com/user-attachments/assets/0a039096-db5a-4783-af1c-8f7a4bc75fc9" />

**Expected behavior**
no top-right ❌ visible when "allow mouse: false" in "AltAppSwitcherConfig.txt"
