Fix CI failure: update Go query request

Failing check:

Lint: contract_test.go:53: sent [GET /users/123 GET /users/456?fields=name&verbose=true POST /items GET /status/404 GET /status/500], want [GET /users/123 GET /users/123?fields=name&verbose=true POST /items GET /status/404 GET /status/500]

Cause: The contract now uses user 456 for the exact query-string request, but two Go client tests still used user 123.

Fix: Update the deliberate request and exact-lookup expectations to the contract's user 456 path.
