test(zoo-gateway): mock cached-token + clear-token auth helpers

The downstream stack (settings-ui) calls getCachedZooCodeToken and
clearZooCodeToken from the auth handler. CI on stacked PRs merges base
into head so this spec runs against the cached-token-aware handler;
expand the auth module mock so the auth guard test exercises the real
throw path instead of vitest's missing-mock-export error.
