test(ai): pin the queue-updated event that now follows stream-error on the failure path (#22500)

## Rationale

main's `server-test` is red: 4 error-path tests in
`stream-agent-chat.job.spec.ts` fail. #22494 made the stream failure
path publish `queue-updated` **after** the terminal `stream-error` (so
background tabs refetch the persisted partial transcript), but these
specs still asserted `stream-error` is the *last* published event.
Classic squash-merge semantic conflict — #22494's branch predated the
spec assertions, both were green in isolation.

## Why this is the right fix (not patching a symptom)

The job behavior is the intended one from #22494; the specs encode the
old contract. Rather than loosening the assertions to "a stream-error
was published somewhere", this pins the full intended terminal sequence
— `stream-error` followed by `queue-updated` — so the convergence event
itself is now regression-tested on all four failure paths (mid-stream
provider error, setup rejection, persistence failure, missing
workspace).

## Impact

Unblocks `server-test` / `ci-server-status-check` for every open PR
(including #22498, which is needed to fix the dev-cluster migration
incident). Test-only change.
