test(e2e): follow send-log status badge markup in scrapers

The deliveries_rows template wraps status in badge spans, but the e2e gate still looked for bare td cells, so send_verify_dkim_and_status timed out even when mail was delivered and logged. Add a handler regression test so go test ./... catches this drift without Docker.
