What is the current bug behavior?

An error appears.

What is the expected correct behavior?

You should be able to edit network policies even if you do not have a policy project, because they are not dependent on having one.

Possible fixes

Have the PolicyConfigurationValidationService skip the policy_configuration checks if the type is container_policy
