louispaulb 512c4a5f1b feat(ops): dispatch auto complet + perf Boîte/rapports + fix session
Planificateur « Suggérer » : 4 stratégies (smart / meilleurs d'abord / équilibré /
juste ce qu'il faut), compétences+niveaux par tech (édition inline), niveau requis
par compétence + par job, carte des tournées (1 couleur/tech, domicile→arrêts,
sélecteur de jour), fenêtre de dispatch auj.+demain (dates sélectionnées), règle
week-end + placeholder « en attente du quart », clustering + lasso + filtre-date
sur la carte, accès rapide « À assigner » (badge).

Boîte : liste /conversations allégée (45 Mo → ~1 Mo, 17×) + messages chargés à
l'ouverture. Rapports : cache SWR sur revenue-explorer (22×). Session : keep-alive
+ timeout fetch global + authFetch durci → fin des rechargements manuels.
