feat(users): allow role assignment for Azure AD and LDAP users

- Backend: add admin-only guard + role validation to PUT /users/{id}
- Backend: prevent admins from changing their own role
- Frontend: role toggle button (person-check / person-dash) per user row
- Frontend: admin badge green, viewer badge secondary, ldap badge blue
- i18n: add makeAdmin / makeViewer translations (de + en)
