feat: Afficher la couleur des matières dans l'emploi du temps élève et parent

L'admin pouvait attribuer une couleur à chaque matière, mais cette couleur n'était utilisée que dans la vue admin de l'emploi du temps. Les APIs élève et parent ne renvoyaient pas cette information, ce qui donnait un affichage générique (gris/bleu) pour tous les créneaux. L'API renvoie désormais subjectColor dans chaque créneau, et les vues jour/semaine/widget/détails affichent la bordure colorée correspondante. Le marqueur "Prochain cours" conserve sa priorité visuelle via une surcharge CSS variable.
