🎯 What has been changed and why do we need it?

Added Kubernetes pod monitoring panels to Grafana dashboard

Changes:

• Added "Unscheduled Pods" panel - tracks pods that cannot be assigned to nodes due to resource constraints or scheduling issues
• Added "Container Issues" panel - monitors containers in CrashLoopBackOff, ErrImagePull, or ImagePullBackOff states

Why we need it:
These panels provide visibility into pod and container health issues that were previously not monitored:

• Unscheduled pods indicate infrastructure problems (insufficient CPU/memory, node selector mismatches, resource quotas)
• Container issues surface application-level problems (crashes, image pull failures, misconfigurations)

Early detection of these issues enables faster incident response and reduces downtime.
