"""Phase 7 — /api/status exposes auth-gate state + AuthWidget integration.

The dashboard's status endpoint now reports ``auth_required`` and
``auth_providers`` so the AuthWidget + StatusPage can render the
correct "gated / loopback" badge without a separate round trip. This
test asserts both shapes (gated and loopback).

The AuthWidget itself is .tsx — no Python test here. The widget's
behaviour (renders nothing on 401, shows truncated user_id, etc.) is
documented in AuthWidget.tsx; covered manually via the Phase 4.2
smoke test against staging Portal.
