This PR adds a new Kubernetes troubleshooting scenario focused on debugging an application that is not accessible despite existing resources.

More About Scenario

The scenario covers two common real-world issues:

  1. Pod CrashLoopBackOff caused by a Secret key misconfiguration
  2. Service not routing traffic due to a targetPort mismatch

Learning Outcomes

  • Debug CrashLoopBackOff using kubectl logs and describe
  • Verify and fix Secret environment variable configuration
  • Understand Service port vs targetPort behavior

The scenario is designed as a single troubleshooting challenge with clear validation logic.
