fix(e2e): accept CONFIG_ERROR (exit 78) in xiaoyuzhou E2E guard (#1066)

PR #1059 migrated xiaoyuzhou from SSR scraping to authenticated API.
The E2E tests run without credentials, producing exit code 78
(CONFIG_ERROR). The existing `isExpectedChineseSiteRestriction` guard
only caught FETCH_ERROR, PARSE_ERROR, and NOT_FOUND — not config
errors from missing auth credentials.
