test(integration): let the server time out a statement before the test does

A statement-level hang in the integration suite surfaced only as a
60-second test timeout, because statement_timeout sat at the same 60 s.
At 45 s the server cancels first, and its error names the statement and
the lock or wait it was stuck on.
