feat(ui): Navigation neu strukturiert (flache Topbar + Verwaltung-Menü + /settings)

Topbar nur noch täglich genutzte Punkte (Dashboard/Zeit/Abwesenheiten/Kalender);
HR/Admin-Funktionen im neuen "Verwaltung"-Dropdown. Zahnrad führt auf eigene
/settings-Seite mit Kategorie-Kacheln statt 11er-Flachliste. Zentrale navConfig.ts
für PRIMARY/MANAGEMENT/SETTINGS_GROUPS; Rollen-Gating unverändert.
