feat: Team-Statistik-Dashboard für Headcoaches

Fügt eine neue Seite hinzu, auf der Headcoaches Statistiken für ihre Teams einsehen können.

Die Statistikseite umfasst:
- W-L-Bilanz, Siegquote (PCT) und aktuelle Serie
- Balkendiagramm für erzielte und zugelassene Runs (RS vs. RA)
- "Luck-O-Meter" zum Vergleich der realen und pythagoreischen Siegquote
- Inning-Heatmap zur Anzeige der erzielten Runs pro Inning

Die Seite ist über einen neuen Button auf dem Dashboard für jedes vom Headcoach trainierte Team erreichbar.
