feat: Implementierung von BaseHttpClientService und DIExtensions für HTTP-Client-Dienste

- Hinzugefügt: `BaseHttpClientService` zur Handhabung von HTTP-Anfragen mit Cookie-Verwaltung. - Implementiert: `HttpClientService<TClientOptions>`, das `BaseHttpClientService` für typisierte Client-Optionen erweitert. - Erstellt: `DIExtensions` zur Registrierung von HTTP-Client-Diensten im Dependency Injection Container. - Bereitgestellt: Methoden zum Hinzufügen von HTTP-Client-Diensten mit und ohne spezifische Client-Optionen. - Konfiguriert: Optionen zum Festlegen der Basis-URI für HTTP-Clients.
