Pull Request Overview

This PR fixes potential nil-pointer dereferences when handling obfuscated secrets across multiple cloud provider configurations. The changes add defensive nil checks before dereferencing secret field pointers to prevent runtime panics.

Key Changes:

• Added nil checks for secret fields before dereferencing them in comparison operations
• Applied consistently across AKS, AWS, Azure, GCP, Kubernetes, and OpenShift configurations
• Prevents nil-pointer panics when secret fields are nil but parent objects exist
