Fix: Correction modal ajout RDV et réorganisation layout

Corrections :

1. Bug modal ajout de rendez-vous :
   - Remplacement des composants Select par des éléments select natifs
   - Les composants shadcn/ui Select ne fonctionnaient pas avec FormData
   - Le modal affichait une page blanche à cause de ce problème
   - Maintenant le formulaire fonctionne correctement

2. Réorganisation du layout :
   - Box Todo et RSS maintenant côte à côte (au lieu d'empilées)
   - Largeur de la colonne droite passée de 380px à 760px
   - Grid à 2 colonnes dans la partie droite
   - Hauteur augmentée : max-h-[calc(100vh-300px)] pour les deux boxes
   - Plus d'espace pour afficher les tâches et articles

3. Amélioration affichage RSS :
   - Suppression de la rotation automatique toutes les 20s
   - Affichage de tous les articles (15) avec scroll
   - Suppression de l'état rssDisplayOffset inutile
   - Suppression du useEffect de rotation
   - Meilleure utilisation de l'espace vertical disponible
