hzhang 94155614f5 feat(auth): OIDC login + identity binding + HARBORFORGE_OIDC_ONLY
- Generic OIDC (Authlib discovery) Authorization Code flow; backend
  issues the existing HS256 JWT on success. Unbound identities are
  rejected (no auto-provisioning).
- User.oidc_issuer/oidc_subject (unique together) + startup migration.
- PUT/DELETE /users/{id}/oidc-binding (admin or account-manager;
  JWT or API key; 409 on conflict). Self-link /auth/oidc/link
  (non-OIDC_ONLY only). Public GET /auth/config.
- HARBORFORGE_OIDC_ONLY: /auth/token rejected, create/update ignore
  password (passwordless users; API keys + OIDC still work).
- Dockerfile ARG/ENV HARBORFORGE_OIDC_ONLY; authlib+itsdangerous deps;
  SessionMiddleware for OIDC state. Fixed _user_response to expose
  the new binding fields.
