chore(wip): consolidation intermédiaire multi-tickets (sprints Statistiques, UI, Bug resolution, Serveur-client)

Regroupe l'état de travail en cours réalisé dans un même worktree sur
plusieurs tickets/sprints (#85, #136, #145, #155-160, #162-164),
mélangeant des tickets QA et inProgress. Ne constitue pas une feature
terminée : commit de sauvegarde avant triage/split par ticket en
branches feature/* dédiées. Exclut les dossiers d'environnement de
build locaux et le heap dump parasite (.gitignore mis à jour).
