Un tableau Grafana pour les cellules, et le plafond du BMS enfin historise

Le GX n'expose que l'agregat du parc : les quinze tensions d'un module
ne sortent que par la console de son BMS. Le tableau les trace, avec
les paliers d'alarme du materiel lui-meme - 3480, 3520, 3550, 3600 mV
- et met la cellule meneuse en regard du plafond de charge.

Le plafond impose par le BMS, grandeur centrale de tout ce diagnostic,
n'etait pas historise : il l'est desormais, comme l'alarme de tension
de cellule. Ils manquaient tous les deux a la memoire.

Les quatre requetes cellule echouent tant que la table n'existe pas ;
elles passeront apres redemarrage du service et import.
