Implement cybernetwork background features: Add routes for serving cybernetwork CSS and JavaScript files, update base.html to include the new CSS and initialization script, and enhance style.css with smooth scrolling and background imports. This update improves the visual experience and functionality of the cybernetwork background in the application.

-
-# Häufige Fehler und Lösungen
-D
-## Content Security Policy (CSP)
-
-### Problem: Externe Ressourcen werden nicht geladen
-**Fehler:** Externe Ressourcen wie CDNs werden nicht korrekt geladen.
-
-**Lösung:**
-1. Stellen Sie sicher, dass die URLs in den Templates korrekt sind:
-   ```html
-   <link href="https://cdn.tailwindcss.com" rel="stylesheet">
-   ```
-
-2. Überprüfen Sie die Netzwerkverbindung und ob die CDN-Domains erreichbar sind.
-
-3. Verwenden Sie lokale Ressourcen als Alternative:
-   ```html
-   <link href="{{ url_for('static', filename='css/tailwind.min.css') }}" rel="stylesheet">
-   ```
-
-### Problem: CSP-Fehler (script-src-elem 'none', font-src 'none', etc.)
-**Fehler:** Skripte werden aufgrund von CSP-Einschränkungen blockiert.
-
-**Lösung:**
-1. WICHTIG: CSP-Einschränkungen NICHT implementieren! Diese sind im Projekt unerwünscht.
-
-2. Falls CSP-Header bereits vorhanden sind, entfernen Sie diese aus der Anwendung:
-   ```python
-   # Entfernen Sie diesen Code, falls vorhanden:
-   # @app.after_request
-   # def add_security_headers(response):
-   #     response.headers['Content-Security-Policy'] = '...'
-   #     return response
-   ```
-
-3. Stellen Sie sicher, dass externe Ressourcen direkt geladen werden:
-   ```html
-   <script src="https://cdn.jsdelivr.net/npm/marked/marked.min.js"></script>
-   <script src="{{ url_for('static', filename='js/alpine.min.js') }}" defer></script>
-   ```
-
-4. Für Inline-Skripte keine Nonce verwenden:
-   ```html
-   <script>
-     // Inline-JavaScript-Code ohne Einschränkungen
-   </script>
-   ```
-
-### Problem: Tailwind CSS CDN wird blockiert
-**Fehler:** Tailwind CSS kann nicht von CDN geladen werden.
-
-**Lösung:**
-1. Verwenden Sie die lokale Version von Tailwind CSS:
-   ```html
-   <link href="{{ url_for('static', filename='css/tailwind.min.css') }}" rel="stylesheet">
-   ```
-
-2. Alternativ können Sie die CDN-Version direkt im Template einbinden:
-   ```html
-   <script src="https://cdn.tailwindcss.com"></script>
-   ```
-
-3. Stellen Sie sicher, dass die Datei `static/css/tailwind.min.css` existiert und aktuell ist.
-
-## Datenbank-Fehler
-
-### Problem: Datenbank existiert nicht
-**Fehler:** SQLite-Datenbank kann nicht geöffnet werden.
-
-**Lösung:**
-1. Datenbank initialisieren: `python TOOLS.py db:rebuild`
-2. Sicherstellen, dass das Datenbankverzeichnis existiert und Schreibrechte hat
-
-## Authentifizierung
-
-### Problem: Login funktioniert nicht
-**Fehler:** Benutzer kann sich nicht einloggen.
-
-**Lösung:**
-1. Standard-Admin-Benutzer erstellen: `python TOOLS.py user:admin`
-2. Passwort zurücksetzen: `python TOOLS.py user:reset-pw -u USERNAME -p NEWPASSWORD`
-
-## Neural Network Background
-
-### Problem: Hintergrund-Animation wird nicht angezeigt
-**Fehler:** Die Neural Network Animation im Hintergrund erscheint nicht.
-
-**Lösung:**
-1. Überprüfen Sie, ob die Datei `static/neural-network-background.js` korrekt eingebunden ist:
-   ```html
-   <script src="{{ url_for('static', filename='neural-network-background.js') }}"></script>
-   ```
-
-2. Initialisieren Sie die Animation im Template:
-   ```html
-   <script>
-     document.addEventListener('DOMContentLoaded', () => {
-       const background = new NeuralNetworkBackground();
-       background.initialize();
-       background.animate();
-     });
-   </script>
-   ```
-
-3. Stellen Sie sicher, dass keine CSS-Regeln die Animation überdecken:
-   ```css
-   #neural-network-background {
-     z-index: -10;
-     opacity: 1;
-   }
-   ```
-
-## Mindmap-Funktionalität
-
-### Problem: Mindmap-Daten werden nicht geladen
-**Fehler:** Die dynamische Mindmap zeigt keine Daten an.
-
-**Lösung:**
-1. Überprüfen Sie die API-Endpunkte für die Mindmap-Daten:
-   ```python
-   @app.route('/api/mindmap/nodes', methods=['GET'])
-   def get_mindmap_nodes():
-       # Implementierung...
-   ```
-
-2. Stellen Sie sicher, dass die AJAX-Anfragen korrekt implementiert sind:
-   ```javascript
-   fetch('/api/mindmap/nodes')
-     .then(response => response.json())
-     .then(data => {
-       // Verarbeitung der Mindmap-Daten
-     });
-   ```
-
-3. Überprüfen Sie die Datenbankeinträge für Mindmap-Knoten und -Verbindungen.
-
-## ChatGPT-Assistent
-
-### Problem: Assistent reagiert nicht auf Eingaben
-**Fehler:** Der ChatGPT-Assistent verarbeitet keine Benutzereingaben.
-
-**Lösung:**
-1. Überprüfen Sie die Einbindung der JavaScript-Datei:
-   ```html
-   <script src="{{ url_for('static', filename='js/modules/chatgpt-assistant.js') }}"></script>
-   ```
-
-2. Stellen Sie sicher, dass der Assistent korrekt initialisiert wird:
-   ```javascript
-   document.addEventListener('DOMContentLoaded', () => {
-     const assistant = new ChatGPTAssistant();
-     assistant.initialize();
-   });
-   ```
-
-3. Überprüfen Sie die API-Endpunkte für die Kommunikation mit dem Assistenten.
