feat: vue détail d'un site (#51)

Ajoute la page de détail d'un site (fiche, mesure instantanée, jauge de consommation, historique) en remplacement du placeholder. Les champs null sont affichés explicitement avec leur raison plutôt que masqués. Ajoute l'endpoint GET /sites/{id}/current côté backend, qui retourne la dernière mesure connue d'un site sans filtre temporel, conformément au contrat de l'issue.
