test: accept provider_family kwarg in regression stubs

Cursor's provider abstraction added tailor_resume_v4(..., provider_family=...).
The regression stubs didn't accept it, so the call threw -> caught as
PROVIDER_ERROR -> READY demoted -> download blocked, failing verify_anticheat
test 1 and verify_90_pipeline. Product code was correct; only the test stubs
were stale. Add **kwargs to the stubs. All three suites pass again.
