Jira issue: CRDB-66894

Start with sql/sqlstats/sslocal/sql_stats_test.go and run TestAssociatingStmtStatsWithTxnFingerprint, focusing on the enabled=false subtest and its condition at line 643. Compare the TeamCity test logs and goroutine dump with the expected value 4 and observed value 7. Done means the test completes successfully with the intended statement-stat association.
