feat(2): Q3.1 partial — lasuite-docs PARITY + health_check + auth_required (Q2.4 still passes)

- tests/lasuite-docs/PARITY.md: parity table for health_check.py (ported);
  oidc_login.py + upload_conversion.py documented as Q3.1 follow-up needing OIDC env wiring;
  ≥2 recipe-specific tests rationale (test_oidc_with_keycloak + test_auth_required).
- tests/lasuite-docs/functional/test_health_check.py: parity port of
  recipe-info/lasuite-docs/tests/health_check.py — HTTP 200/301/302 from root.
- tests/lasuite-docs/functional/test_auth_required.py: NEW recipe-specific —
  GET /api/v1.0/users/me/ asserts 401/403 (auth required). Non-vacuous: distinguishes
  correctly-wired OIDC gate from anonymous access (200), missing route (404), broken (5xx).

The Q2.4 acceptance test (test_oidc_with_keycloak.py) continues to verify the dep resolver +
SSO harness against the per-run keycloak dep (F2-5 fix verified cold; see ccci-f25-verify.log).

+"""lasuite-docs — recipe-specific functional test (Phase 2 P3, ≥2 beyond parity).
+
+The defining property of lasuite-docs as configured by the recipe is that its **backend API is
+auth-protected** — OIDC tokens authorize access; anonymous requests are rejected. This test
+proves the auth middleware is wired correctly: a sample backend endpoint (`/api/v1.0/users/me/`)
+returns 401 Unauthorized without a token. Non-vacuous: a misconfigured backend serving anonymous
+access would return 200; a broken auth middleware would return 500; a wrong route would return
+404 — only a correctly-wired OIDC gate returns 401.
+
+Distinct from the OIDC password-grant test against the keycloak dep (`test_oidc_with_keycloak`):
+this proves **lasuite-docs's** own auth posture; that test proves the **SSO provider** can issue
+tokens. Together they exercise both sides of the OIDC flow's plumbing.
+
+Runs in the custom tier against the shared post-install deployment.
