Drop the lease, heartbeat, and stale-recovery test coverage that no
longer applies, and add coverage for the new behaviour: graceful

in AWAITING_APPROVAL, and SubmitApproval merging decisions and
requeuing the run. Exercise the submitAgentRunApproval mutation end to
end, including the authorization paths for the relocated policies.
