test(agent-status): make the notification-id test fail on the pre-fix ordering

The stored row inherited the helper's default codex agentType while the event
named claude, so agentSnapshotMatchesExplicitTitle dropped it and
freshStoredAgentStatus was undefined — the assertion held under either side of
the `??`. Name the stored row's agent so the pinned working row survives and
the snapshot-first precedence is what the test actually pins.
