Resumes a decided agent approval's run through its thread object. An
implementation sends expectedSuspensionFor(record) with the resume, so a
decision for an earlier suspension of the step is refused; without it the
resume is unchecked. A run that has ended rejects with a 409 whose
reason.code is RUN_NOT_SUSPENDED when the context's principal started
it, and with a 404 RunRouteError otherwise.
