Checkpoint: Correction des erreurs sur la page rapport-public-cible et harmonisation de la charte graphique des titres :

**Corrections d'erreurs :**

1. **Erreurs SQL DATE_FORMAT corrigées** (analyticsDb.ts) :
   - Remplacement des sous-requêtes corrélées par des JOIN dans getTauxRemplissageByMonth()
   - Utilisation de COUNT(CASE WHEN...) au lieu de SUM(SELECT COUNT(*))
   - Ajout de leftJoin pour éviter les erreurs de sous-requêtes

2. **Erreur React "Cannot read properties of null" corrigée** (AdminRapportPublicCible.tsx) :
   - Ajout de l'opérateur null-safe `?.` pour accéder à `insc.apprenant?.fonction`
   - Vérification explicite si la fonction est null/undefined
   - Gestion du cas "public cible = tous" qui correspond toujours

3. **Tests réussis** :
   - Page rapport-public-cible : affiche correctement les statistiques et recommandations
   - Tableau de bord analytique : graphiques et statistiques fonctionnels
   - Page suivi questionnaires : affiche correctement les données

**Harmonisation charte graphique :**

- Application du style bleu clair (#6B9FE8) avec ombre portée à tous les titres des 32 pages
- Création de la classe CSS `.page-title` réutilisable dans index.css
- Cohérence visuelle sur toute l'application

**Résultat :**
✅ Toutes les erreurs SQL et React sont corrigées
✅ Les pages fonctionnent correctement sans erreur
✅ Charte graphique harmonisée sur toutes les pages
