feat: Permettre à l'enseignant de saisir les notes dans une grille inline

L'enseignant avait besoin d'un moyen rapide de saisir les notes après
une évaluation. La grille inline permet de compléter 30 élèves en moins
de 3 minutes grâce à la navigation clavier (Tab/Enter/Shift+Tab),
la validation temps réel, l'auto-save debounced (500ms) et les
raccourcis /abs et /disp pour marquer absents/dispensés.

Les notes restent en brouillon jusqu'à publication explicite (avec
confirmation modale). Une fois publiées, les élèves les voient
immédiatement ; les parents après un délai de 24h (VisibiliteNotesPolicy).
Le mode offline stocke les notes en IndexedDB et synchronise
automatiquement au retour de la connexion.

Chaque modification est auditée dans grade_events via un event
subscriber qui écoute NoteSaisie/NoteModifiee sur le bus d'événements.
