fix(nav): keep mobile More-menu labels on one line

Trim the longest label ('Benachrichtigungen') with truncate (nowrap +
ellipsis) instead of break-words so every More-hub tile reads on a
single line on a phone, matching its neighbours. The full label stays
discoverable via the title attribute; the desktop layout is untouched.
