Fix the KVM terminal screen not displaying

During the upgrade to Vue 3 [1], the initialization of the selector,
including the definitions of height, display type, background, overflow,
etc., was ignored, resulting in the KVM screen not displaying the
terminal interface. This commit helps to import these properties for the
KVM from the _kvm.scss file to fix bug [2].

Tested:
 1. Go to the OBMC web page.
 2. Go to the KVM page and check that it works normally
 3. By minifying and zooming in on the web browser, the KVM screen
    adjusts automatically.
 4. Switch between different pages.
 5. Return to the KVM page and check that it works normally.
