feat: Affectation des enseignants aux classes et matières

Permet aux administrateurs d'associer un enseignant à une classe pour une matière donnée au sein d'une année scolaire. Cette brique est nécessaire pour construire les emplois du temps et les carnets de notes par la suite. Le modèle impose l'unicité du triplet enseignant × classe × matière par année scolaire, avec réactivation automatique d'une affectation retirée plutôt que duplication. L'isolation multi-tenant est garantie au niveau du repository (findById/get filtrent par tenant_id).
