feat(dashboard-admin): connect admin dashboard to real API data (Ticket #92)

- Frontend:
  - Create UserService to handle user-related API calls (gestionnaires, parents, AMs, admins)
  - Update AdminDashboardScreen to use dynamic widgets
  - Implement dynamic management widgets:
    - GestionnaireManagementWidget
    - ParentManagementWidget
    - AssistanteMaternelleManagementWidget
    - AdminManagementWidget
  - Add data models: ParentModel, AssistanteMaternelleModel
  - Update AppUser model
  - Update ApiConfig

- Backend:
  - Update controllers (Parents, AMs, Gestionnaires, Users) to allow ADMINISTRATEUR role to list users
  - Note: Gestionnaires endpoint is currently bypassed in frontend (using /users filter) due to module import issue (documented in docs/92_NOTE-BACKEND-GESTIONNAIRES.md)

- Docs:
  - Add note about backend fix for Gestionnaires module
  - Update .cursorrules to forbid worktrees
