Assert exactly one failed-email alert for the won safeFail flip.

The LessOrEqual(..., 1) check also passes when safeFail sends no alert. That is a wrong result for this race. The flip to failed wins the compare-and-set, so the row must alert once. A regression that drops the safeFail alert would still pass this test.

Suggested fix 
-		assert.LessOrEqual(t, len(failedMail.all()), 1, "the race must not alert twice for one row")
+		assert.Len(t, failedMail.all(), 1, "the won safeFail flip alerts once for the row")

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

around lines 91 - 108:
Update the alert-count assertion after safeFail in the race test to require
exactly one recorded failed-email alert. Keep the existing counted and
recovered-status assertions unchanged.
