fix: replace bare except with Exception handler in Kubernetes client init (#1265)

The bare except clause in the Kubernetes client initialization block
caused a NameError crash when initialization failed. If KrknKubernetes()
raised an exception before kubecli was assigned, the except handler
attempted to call kubecli.initialize_clients(None) on an undefined
variable, masking the original error entirely.

Replaced the bare except with except Exception as e to:
- Log the actual initialization error for visibility
- Initialize both kubecli and ocpcli with None kubeconfig as fallback
  so subsequent code referencing these variables does not crash
- Avoid catching SystemExit and KeyboardInterrupt unintentionally

Fixes #1264
