Chantier : le bilan lit la courbe horaire au lieu de l'enveloppe

RESOURCE_ESTIMATE consomme desormais la courbe horaire publiee par le workflow
de prevision : forme et magnitude d'un seul tenant, sur 6 jours, avec les trois
plans reels et sans censure. Plus de repartition au prorata, plus de
renormalisation — le noeud se simplifie.

L'enveloppe est retrogradee en repli, utilisee seulement si la courbe est
absente ou vieille de plus d'une heure, le champ `mode` disant laquelle a
servi. Elle garde un role de repere de vraisemblance mais n'ecrete PLUS la
prevision : etant minoree l'apres-midi, elle tronquerait a tort une prevision
correcte.

Piege corrige au passage : le nouveau champ `source` entrait en collision avec
l'objet `source` deja present dans la sortie et etait silencieusement ecrase.
Renomme en `mode`.

Suite portee a 35 scenarios (courbe fraiche lue telle quelle, courbe perimee
basculant en repli).
