feat(cxl-ui): re-implement navigation bar

[freudFlintstone]

https://app.clickup.com/t/86ayah2zr

POC for navigation component using vaadin-menu-bar instead of vaadin-tabs, aiming to have a standard context menu UI.
Because the menu-bar component also uses vaadin-context-menu under the hood, it looks and behaves largely the same as the current custom implementation, even with little CSS work.
Initial implementation brings the navigation component down from nearly 700 lines of code to about 80. If this is used in place of the current component, a lot of CSS can also be cleaned up.

WPS

For given template changes:

This is the result. On the left old menu, right new.

I'll update my branch to get rid of the old component and avoid WPS changes. I have 110 places to check in aybolit, so it will take me a little while.
@pawelkmpt Also, what are those extra menu items? Is there a way I should be looking to filter them out? There doesn't seem to be like that in the old component.

"After categories" came from other menu tree.
Top arrows -> IDK

@pawelkmpt The old component is now completely gone, including any styles in cxl-ui and cxl-lumo-styles that were realted to it. The odd menu items, however, need more investigating, and possibily some database cleanup. It's also likely there are WPS styles overriding the color of the text on the global bar.

Task linked: CU-86ayraehj Front-end bit of nav bar facelift

[pawelkmpt]

This got messy. I locally did git rebase --ff master and don't have recent master commits mixed with this branch

Hum, something definitely odd happened here:

It was still a mess. I cleaned, rebased and force pushed @freudFlintstone
