Pull request overview

This PR removes the "Paused" lifecycle state from the ClusterExtensionRevision API, simplifying the lifecycle model to only support "Active" and "Archived" states. The removal is comprehensive, eliminating the constant definition, related controller logic, and boxcutter integration code.

• Removed the ClusterExtensionRevisionLifecycleStatePaused constant and its documentation
• Removed controller logic that handled paused state (boxcutter WithPaused option)
• Simplified revision filtering logic to only skip archived revisions
