fix: update AUTH0 connection handling to respect include list

- Adjusted logic to ensure 'enterprise-saml' is not marked for deletion when not in the include list.
- Modified tests to reflect that 'google-oauth2' should not be deleted if it's not in the include list.
- Updated behavior to only delete managed connections when assets are empty, preserving unmanaged ones.
- Ensured that unmanaged connections are ignored during updates, preventing unintended deletions.
