Restore global logger state in tests (dependabot#211)

Tests in several packages redirect the process-wide standard logger to capture output. Most did not restore the previous writer, so later tests could inherit a buffer owned by an earlier test. One OIDC registry test restored `os.Stderr` rather than the actual previous writer. `TestSetupLogging` also exercised production code that changes both standard-log and Logrus global configuration without restoring either logger.
