Jira issue: CRDB-68368

Start with pkg/sql/sqlstats/insights/integration/insights_test.go, especially TestFailedInsights and the failure at line 466, then rerun the test with the reported race and shard parameters. Inspect the linked invocation and captured TestFailedInsights logs, including the test_server_shim.go guidance. Done means the integration test completes without the get-user-session membership timeout.
