PR Summary

• Fix for Issue If a top menu entry opens a modal box, don't mark it as active when clicked #6863
  The update provides a solution for a previously reported problem. If a button on the main navigation menu opened a popup window, the system wrongly marked this button as 'active'. This was confusing for users as 'active' usually refers to the currently opened page.

• Updates in humhub.ui.navigation.js
  Changes have been made to the logic that controls how menu items behave when clicked. Specifically, we've made it so that certain menu items (which are identified by their IDs or other attributes) don't get marked as 'active' when clicked. So, if a menu item is meant to open a separate window or action, it won’t give a false impression of being the current page.

@luke- this PR fixes the issue with top menu entries opening the page in a modal box.

I've also replaced the if (!$this.is('#space-menu') && !$this.is('#top-dropdown-menu')) with :not(#space-menu):not(#top-dropdown-menu) in the CSS search. If you think it's not a good idea, I can revert this.

Use case:

$topMenu->addEntry(new MenuLink([
    'url' => '#',
    'htmlOptions' => [
        'data-action-click' => 'ui.modal.load',
        'data-action-click-url' => Url::to(['/my-module/index/index']),
    ],
    ...
]));

Thanks.
