Code Review

This pull request adds the is_deactivated field to the DeviceSerializer metadata fields. However, the reviewer noted that this field is not defined on the underlying Device model or within the serializer itself, which will cause Django Rest Framework to raise an AssertionError during initialization. The field needs to be properly defined to resolve this issue.
