feat: Dashboard placeholder avec preview Score Sérénité

Permet aux parents de visualiser une démo du Score Sérénité dès leur
première connexion, avant même que les données réelles soient disponibles.
Les autres rôles (enseignant, élève, admin) ont également leur dashboard
adapté avec des sections placeholder.

La landing page redirige automatiquement vers /dashboard si l'utilisateur
est déjà authentifié, offrant un accès direct au tableau de bord.
