feat(mobile): consolidation modules epargne, messaging, organisations

- Epargne: badge LCB-FT (bouclier ambre) sur comptes avec fonds bloques + note recap
- EpargneDetail: historique pagine (page/size), affichage soldeAvant/soldeApres/motif dans chaque transaction, bouton "Charger plus"
- TransactionEpargneRepository: getByCompte accepte page et size, gere reponse paginee Spring (content[])
- MessagingDatasource: markMessageAsRead silencieuse (pas d'endpoint unitaire), getUnreadCount somme unreadCount des conversations
- OrganizationDetail: _memberCount charge le vrai nombre depuis GET /membres/count, affiche la valeur reelle au lieu de nombreMembres (toujours 0)
