Add full admin user editing flow: introduce EditUserDialog component and integrate it into AdminUserDetail (with minor copy and button variant tweaks), plus layout tweaks to animate the account chevron. Implement updateAdminUser(...) in GUI services to PATCH /auth/user/{id} with comprehensive error handling and export FORBIDDEN_NOT_ADMIN_MESSAGE. Server-side AppUserController now prevents deactivating users in the Admin role and returns a 403, ensuring admin accounts cannot be disabled. These changes enable editing usernames and activation status from the admin UI while protecting admin accounts.
