fix(frontend): isole les fichiers de tests vitest pour eviter la pollution de mocks

le mock chart.js d'un fichier pouvait ecraser celui d'un autre selon l'ordre
d'execution.

 | **API4, lectures de séries temporelles** | **ouvert** | Pas encore d'endpoint métier, donc ni pagination plafonnée, ni fenêtre temporelle maximale, ni `statement_timeout`. C'est la façon la plus probable dont la démonstration tombera : une requête sur dix ans d'historique suffit. |
 | **API8 Security Misconfiguration, transport** | **ouvert** | Pas de TLS, donc ni HSTS, ni cookie `Secure` réellement posé en production. Ils appartiennent au terminateur TLS, qui n'existe pas. |
 | **API10 Unsafe Consumption of APIs** | **ouvert, et spécifique à ce projet** | L'API Mock de l'école n'a aucune authentification, tourne en HTTP clair sur le réseau de l'école, et expose un endpoint mutatif à quiconque. Sa réponse doit être traitée comme une entrée hostile : bornes physiques, taille de tableau plafonnée, timeout, et frontière d'anti-corruption. La conséquence la plus sérieuse n'est pas la fausse alerte, c'est l'empoisonnement du jeu d'entraînement du modèle de prédiction. |
