Le bilan n expose plus que des nombres
L'API Grafana, enfin accessible, a montre que le serveur renvoyait bien une ligne de valeurs au panneau : le defaut etait donc dans le rendu, pas dans la donnee. Restaient deux elements que le panneau « Sur la periode » des vehicules, lui fonctionnel, n'a pas : une colonne de texte dans le resultat, et un override `custom.hidden` pose pour la masquer — propriete qui n'existe pas sur un panneau stat. Les deux disparaissent. Le GROUP BY, lui, reste necessaire et s'ecrit desormais sur une expression constante, `GROUP BY (1 = 1)`, qui ne demande aucune colonne dans le SELECT. PostgreSQL refuse `GROUP BY true` (non-integer constant) mais accepte cette forme. Verifie par l'API sur la fenetre « Last 24 hours » : sept champs, tous de type number, valeurs presentes.
