Failed OIDC, magic-link, and SAML sign-ins sent users to /auth/error
without the post-login destination, so Sign in dropped OAuth flows
and deep links. Propagate a validated continue query through auth
error redirects, recover it from OIDC state when the IdP denies or
cancels login, and forward it from AuthErrorPage to /auth/login.
