Implement activation checks across various commands and queries

- Introduced `IRequiresActivation` interface to enforce activation requirements for multiple commands and queries, ensuring that only activated users can create, edit, or access configurations, news, and applications.
- Updated the `RequireActivationBehavior` to handle activation checks uniformly, returning appropriate errors for unauthenticated or inactive users.
- Enhanced error handling by adding `NotActivated` error to provide clear feedback for users attempting to access restricted features.
- Updated documentation to reflect the new activation requirements and their implications on user access and functionality.
