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.
