Implémenter la fonctionnalité de téléchargement des certificats depuis le dashboard

Ce commit introduit la possibilité pour vous de télécharger les fichiers de certificats (racine, intermédiaire, final) et la clé privée du certificat racine (administrateurs uniquement) directement depuis la page du tableau de bord.

Changements inclus :
- Ajout d'une méthode `download()` dans `CertificateController` pour gérer la logique de téléchargement sécurisé des fichiers.
- Ajout d'une nouvelle route `GET /certificates/download`.
- Correction et standardisation des liens de téléchargement dans la vue du dashboard pour assurer la transmission correcte des paramètres (type de certificat, nom de fichier, périmètre).
- La méthode de téléchargement inclut la journalisation des tentatives et des erreurs, ainsi que la gestion des permissions pour la clé privée racine.
