fix: errores de compilación - rethusValidated requerido y refreshUser void

- professional_form_provider: agregar rethusValidated al constructor Profesional
- professional_provider: agregar rethusCode y rethusValidated al fallback del constructor
- profile_view: quitar await de refreshUser() que retorna void
