// Regression guard for: the /internal/login-alert route was registered
// after the global JWT auth middleware, so every service-to-service login
// alert got rejected with 401 before the route's own IP+token check ever
// ran. Spinning up the full metrics-service Express app (DB, SSH clients,
// polling managers, etc.) just to hit this one route is out of scope, so
// this asserts the registration order directly against the source instead.
