test(issue-18): measure the wall-clock close on the record and widen the loop worker's wall clock

Both tests ran against the public broker with second-scale budgets: the
error publish after the close can take 10-20 s, and a worker's `started`
must land before a 12 s wall clock. Assert the close time from the record's
updated_at and give the loop scenario a 30 s wall clock.
