test(provider): regen golden snapshot + bump family-count for Chenzk gateway

The Chenzk provider added in a616b88c9 registered a new APIKEY_PROVIDERS
entry (gateways.ts) but did not update the two characterization tests
that assert exact provider counts: the translate-path golden snapshot
(missing the chenzk entry) and the 167-entry family-merge count in
providers-constants-split.test.ts (now 168, verified as a strict
partition sum across the 6 family files, no loss/dup).
