Aligné avec le backend MessagingResource : - Nouveau module communication (conversations, messages, participants) - Respect des ContactPolicy (qui peut parler à qui par rôle) - Gestion MemberBlock (blocages individuels) - UI : conversations list, conversation detail, broadcast, tiles - BLoC : MessagingBloc avec events (envoyer, démarrer conversation rôle, etc.)
