feat: RBAC Phase 5 - Rollenverwaltung im Frontend

Neue /settings/roles-Seite (Aktiv/Historie, Karten-Grid) zum Anlegen,
Bearbeiten, Deaktivieren und Reaktivieren von Rollen mit einer
Rechte-Matrix (nach Bereich gruppierte Checkboxen, Gruppen-Toggle,
Live-Zaehler), passend zum Backend aus Phase 1-3.

- AuthContext liest Rolle/Rechte jetzt ueber GET /auth/me statt aus
  dem JWT (das seit Phase 3 keinen role-Claim mehr traegt); neue
  hasPermission()-Hilfsfunktion ersetzt String-Vergleiche gegen "ADMIN".
- Sidebar zeigt Verwaltungs-Eintraege jetzt einzeln nach Berechtigung
  (statt Alles-oder-Nichts fuer ADMIN), inkl. neuem "Rollen & Rechte"-
  Eintrag.
- Settings-Layout blockt nur noch, wenn gar keine Verwaltungs-
  Berechtigung vorhanden ist, statt stur auf die ADMIN-Rolle zu pruefen.
- Benutzerseite: Rollen-Auswahl laedt jetzt aktive Rollen von
  GET /roles statt einer festen 5-Werte-Liste; sendet roleId statt
  role an POST/PATCH /users.
- Totes jwt.ts (Rolle wurde bislang aus dem Token dekodiert) entfernt.

Live im Browser getestet (Login, Sidebar, Rollen anlegen/bearbeiten/
deaktivieren/reaktivieren, Benutzer-Dialog): dabei einen echten a11y-
Bug gefunden und behoben - Gruppen-Checkboxen fuer mehrwortige
Bereichsnamen ("Wiederkehrende Aufgaben", "Rollen & Rechte") hatten
keinen zugaenglichen Namen, weil die HTML-id ein Leerzeichen enthielt;
jetzt ueber einen Slug erzeugt.

Verifiziert: tsc, lint, build, alle Unit-Tests (14/14) gruen.
