apiFetch now redirects to /login.html when the server returns 401, so
flipping AUTH_ENABLED=true on mam-api gives the user the login screen
instead of a half-loaded app that silently failed to fetch /auth/me.
While AUTH_ENABLED=false the server's /auth/me still returns a synthetic
200 user, so this branch is dormant — safe to deploy ahead of the env
flip on the server. After the flip the operator visits /login.html
(directly or via auto-redirect), runs the "Create admin account" flow
once, and lands back on the SPA with a real session.
Guards against a redirect loop if login.html itself somehow lands here.
