fix: correct test assertion for HTTP 429 status code

The test was expecting status to be 500, but the repository correctly
returns the actual HTTP failure code (429). Updated the test assertion
to match the actual behavior, which is consistent with the repository
implementation that returns (failure.code ?: HTTP_500).
