Flux durch TallStackUI 4 ersetzt

- TallStackUI 4 (MIT) statt Flux; Komponenten mit Präfix ts- (<x-ts-…>)
- Layouts, Login-, Passwort-, 2FA- und Einstellungsseiten neu aufgebaut
- Livewire-Skripte explizit in beiden Layouts, damit Alpine auch auf den
  Fortify-Seiten ohne Livewire-Komponente läuft
- Dark Mode über tallstackui_darkTheme(), ohne Aufblitzen beim Laden
- Registrierungs-View und ungenutzte Layout-Varianten entfernt
- Test: Seiten laden keine Ressourcen von fremden Hosts (Vorgabe "alles lokal")
