Füge Unterstützung für SSL/TLS in die Konfiguration und das Build-System ein

- Integriere die libwebsockets-Bibliothek für SSL/TLS WebSocket-Unterstützung in `CMakeLists.txt`.
- Aktualisiere `chatconfig.json`, um SSL-Optionen wie `ssl_enabled`, `ssl_cert_path` und `ssl_key_path` hinzuzufügen.
- Ergänze das `deploy.sh`-Skript um einen Schritt zur optionalen Einrichtung von SSL/TLS.
- Modifiziere `update_config.sh`, um die SSL-Konfiguration in die Servereinstellungen zu integrieren.
- Implementiere eine Überprüfung in `main.cpp`, um den SSL-Status zu prüfen und entsprechende Meldungen auszugeben.
