feat: Permettre l'import d'élèves via fichier CSV ou XLSX

L'import manuel élève par élève est fastidieux pour les établissements qui gèrent des centaines d'élèves. Un wizard d'import en 4 étapes (upload → mapping → preview → confirmation) permet de traiter un fichier complet en une seule opération, avec détection automatique du format (Pronote, École Directe) et validation avant import. L'import est traité de manière asynchrone via Messenger pour ne pas bloquer l'interface, avec suivi de progression en temps réel et réutilisation des mappings entre imports successifs.
