What changed

Corrected the providerUsageLimitCheckJob test description from rearams to re-arms.

Why this change was made

The test title contained a high-confidence spelling typo, which made the developer-facing description inaccurate.

Impact

No runtime behavior changes. The focused BullMQ test suite continues to pass, and the test now accurately describes the threshold re-arming behavior.
