Reject a null credential configuration.

The CRD preserves config without a type constraint, and its oneOf rule only requires the field to be present. Therefore, config: null can reach the translator. json.Unmarshal accepts it and leaves authConfig nil.

Reject a nil map after decoding and add a null regression case.

Review comment at @internal/adc/translator/consumer.go at line 66:
After json.Unmarshal decodes credentialSpec.Config.Raw into authConfig, reject a
nil map with a contextual error before assigning it to credential.Config; add a
regression case verifying that config: null is rejected.
