feat: WebSocket temps réel + Finance Workflow + corrections

- Task #6: WebSocket /ws/dashboard + Kafka events (5 topics)
  * Backend: KafkaEventProducer, KafkaEventConsumer
  * Mobile: WebSocketService (reconnection, heartbeat, typed events)
  * DashboardBloc: Auto-refresh depuis WebSocket events

- Finance Workflow: approbations + budgets (backend + mobile)
  * Backend: entities, services, resources, migrations Flyway V6
  * Mobile: features finance_workflow complète avec BLoC

- Corrections DI: interfaces IRepository partout
  * IProfileRepository, IOrganizationRepository, IMembreRepository
  * GetIt configuré avec @injectable

- Spec-Kit: constitution + templates mis à jour
  * .specify/memory/constitution.md enrichie
  * Templates agent, plan, spec, tasks, checklist

- Nettoyage: fichiers temporaires supprimés
