Améliore la lisibilité de la Détection de triche sur /admin

Ajoute l'avatar du joueur signalé (admin_list_members() le renvoyait déjà, juste jamais propagé), l'heure de début/fin de la partie (déduite de created_at et de la durée annoncée), et remplace la ligne de détails en flex-wrap par une grille à étiquettes qui reste lisible sur mobile.
