Baustein 8: Settings-Tab "Synchronisation" (Kapitel 10)

Browse Source 
Neuer Tab in den Einstellungen: Server-URL, Login, Verbindungstest,
Logout.

- Neu SyncSettingsService (Muster AiSettingsService): Token
  AES-256-verschluesselt ueber SyncCrypto mit eigenem, rein lokalem
  Schluessel - ersetzt die bisherigen Klartext-Helfer
  AppBootstrapper.LoadServerUrl/SaveServerUrl und die unverschluesselte
  auth.token-Datei
- Neu SyncAuthService fuer den Login-HTTP-Aufruf gegen /api/auth/login
  und den Verbindungstest (unterscheidet erreichbar & angemeldet /
  erreichbar aber nicht angemeldet / nicht erreichbar)
- Speichern/Anmelden startet die App neu (AppBootstrapper.
  RestartApplication, gleiches Muster wie bei DB-Passwort/AppLock-
  Aenderungen) - SyncEngine/SnapshotService werden nur einmalig beim
  Start registriert, es gibt keinen Live-Re-Registrierungspfad
