test(external-migrate): add scheduleEntryAction api_version header assertions

Covers all four publish/unpublish paths (entry publish, entry unpublish,
asset publish via sys_assets, asset unpublish via sys_assets) and verifies
api_version: '3.2' is present in headers on every call. Also asserts
branch header inclusion and omission.
