A tab in Insights is active even if it's the only one

[maxcold]

Motivation

On Expanded flyout it might happen that only one of the current Insights tab is available, either Misconfigurations or Vulnerabilities. But even the tab is the only one it looks like it does smth as presented as enabled button. We need to either not show the tab or make it disable, consult with designers on this one

Definition of done

• Single tab should not mislead users into thinking that clicking on it does smth

Out of scope
