Broken layout elements in monitoring

[Etheryte]

Part of https://github.com/SUSE/spacewalk/issues/18940

All urls below are specified as the dev proxy (yarn proxy https://...), since that's the most convenient way to work on these issues.

To switch between the new theme and the old theme in the console: debugUtils.toggleUpdatedTheme()
To switch between the Suma theme and the Uyuni theme: debugUtils.toggleTheme()

Probably related to the column bug we're already fixing under another ticket, but good to track this separately just in case.

Definition of done

The updated theme has no visual bugs, all related page urls are added to ViewHelper.java and view-helper.ts.
