Subject: [PATCH] Normalize collections in WorkflowManagementFeature

This commit ensures uniqueness within the 'ActivityTypes' and 'VariableDescriptors' collections in the WorkflowManagementFeature. 'ActivityTypes' has been updated to only add distinct activity types, and 'VariableDescriptors' has been refined to only add descriptors with unique 'Type' properties.
