This change improves the reliability of Calico network cleanup operations by preventing them from running during cluster hibernation or state transitions. The modification consolidates hibernation state checking logic and removes an unnecessary parameter from the cleanup function.

Walkthrough

• Bug Fix: Enhanced Calico network cleanup logic to avoid running during cluster hibernation or transition states (hibernating/waking up), preventing potential conflicts and ensuring cleanup only occurs when the cluster is in a stable, active state
• Refactor: Simplified the cleanup function signature by removing the cluster parameter and moving hibernation checks to the caller, improving code organization and reducing redundant state validation
