- 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
