test(run-ops split): assert expireRun completes the run when resolveEnv is null

The review fix (c9237f5) took env resolution off the expireRun path: org/
project/environment identity now comes from the run's latest execution
snapshot, so the run is fully expired (message acked, waitpoint completed to
unblock any parent, runExpired emitted) even when the control-plane resolver
returns null. The old test still encoded the pre-fix contract (no event, no
ack) and asserted expiredEvents.length === 0. Update it to assert the
graceful-degradation contract the fix intends.
