Subject: [PATCH] Feat: Supporter-Team-Statistiken in der Team-Statistikansicht
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Erweitert die Team-Statistikansicht um zwei neue Metriken:
- 'Games with Supporters': Zeigt die Anzahl der Spiele an, die mit Unterstützung
  durch ein zweites Team (Supporter-Team) stattgefunden haben.
- 'Avg. Supporter Share': Berechnet den durchschnittlichen Prozentsatz der
  Spieler, die in diesen Spielen vom Supporter-Team gestellt wurden.

Diese Statistiken helfen, den Grad der Abhängigkeit von externer Spielerunterstützung
zu analysieren. Die Anzeige erfolgt in einer neuen Karte auf der Team-Statistikseite.

Änderungen umfassen:
- Anpassung der Funktion  in
  zur Berechnung der neuen Metriken unter Berücksichtigung von
   und .
- Erweiterung des Templates
  um eine neue 'Supporter Stats'-Karte zur Anzeige der berechneten Werte.
