Wizard-Hoehe fix, Logout in Konto, Server-Reset, responsive Tabs, Set-Zeilen, Brand-Date

- Wizard: feste Hoehe (600px, intern scrollbar), Schritt-Inhalt zentriert
  (.wizard-body) -> Schritte gleich gross, auch beim User anlegen
- Benutzer-Anlage: Bestaetigung 'Benutzer x angelegt.' (ohne 'Weiter mit'),
  Solo-Option nach User-Anlage deaktiviert (kein irrefuehrendes Umschalten)
- User-Chip + Abmelden aus der Topbar entfernt, 'Abmelden' in Konto-Sektion
- Topbar-Datum: 'Fr 02.10.2026' + aktive Session ('Push aktiv') statt
  redundantem 'Today'
- Tabs: flex-wrap statt Scrollen, auf Mobil volle Breite + kompakter
- Server-Reset (Owner): Passwort + 'RESET'-Eingabe, loescht alle Daten
- Benutzerliste: Querbalken vor dem Anlegen-Formular
- Tests: 163 Checks gruen (39+18+49+32+25)
