"""First-run install wizard.
`GET /api/setup/status` is public (the SPA uses it to decide whether to show the wizard). Every
mutating step goes through `require_setup`: it rejects once the instance is configured AND requires
the one-time setup token (printed to the container logs at first boot, carried by the wizard as the
X-Setup-Token header). The wizard steps themselves are added in epic 6c.
