"""Phase 1: service-credential-set admin endpoints (real app, real HTTP).

These import the actual web_server app and drive the endpoints through a Flask
test client — the only way to verify the @admin_only gating and the request
validation wrappers for real. Secrets must never come back in any response.

Heavy (imports web_server once), so isolated in its own module. The default
session is profile 1 (admin); a non-admin session is simulated to prove the
gate blocks writes.
