feat: Permettre à l'élève de consulter ses notes et moyennes

L'élève avait accès à ses compétences mais pas à ses notes numériques.
Cette fonctionnalité lui donne une vue complète de sa progression scolaire
avec moyennes par matière, détail par évaluation, statistiques de classe,
et un mode "découverte" pour révéler ses notes à son rythme (FR14, FR15).

Les notes ne sont visibles qu'après publication par l'enseignant, ce qui
garantit que l'élève les découvre avant ses parents (délai 24h story 6.7).
