fix(e2e-cli): use config timeout for queue drain wait

The CLI was using a hardcoded 30s timeout for waitForQueueDrain,
which is shorter than a single Retry-After: 60 cycle. Events
rate-limited near the end of a test run would be dropped because the
process exited before the retry fired.

Now uses config.timeout (default 120s) so the drain wait accommodates
at least one full retry cycle.
