Feature: Améliorations UI des boxes Todo, RSS et Calendrier

Modifications :

1. Box Flux RSS :
   - Correction du bug d'affichage de l'entête (boutons plus compacts)
   - Affichage de seulement 3 articles à la fois
   - Rotation automatique toutes les 20 secondes parmi les 15 derniers articles
   - Indicateurs de pagination (dots) pour visualiser la rotation
   - Taille de texte réduite pour plus de lisibilité

2. Box Todo List :
   - Interface plus compacte pour afficher plus de tâches
   - Padding réduit (p-2 au lieu de p-3)
   - Taille de texte réduite (text-sm)
   - Espacement vertical réduit (space-y-1.5 au lieu de space-y-3)
   - Hauteur maximale augmentée de 400px à 350px
   - Boutons et icônes plus petits

3. Box Calendrier :
   - Ajout d'une icône bleue animée (pulse) pour les RDV du jour
   - Meilleure identification visuelle des événements d'aujourd'hui
