feat: Setup KIND cluster for local Kubernetes development

- Created 5-node KIND cluster (1 control-plane + 4 workers)
- Configured NodePort mappings for console access (30080, 30081)
- Created namespace separation (site11-console, site11-pipeline)
- Deployed MongoDB and Redis in KIND cluster
- Deployed Console backend and frontend with NodePort services
- All 4 pods running successfully and verified with browser test

Infrastructure:
- k8s/kind-dev-cluster.yaml: 5-node cluster configuration
- k8s/kind/console-mongodb-redis.yaml: Database deployments
- k8s/kind/console-backend.yaml: Backend with NodePort
- k8s/kind/console-frontend.yaml: Frontend with NodePort

Management Tools:
- scripts/kind-setup.sh: Comprehensive cluster management script
- docker-compose.kubernetes.yml: Monitoring helper services

Documentation:
- KUBERNETES.md: Complete usage guide for developers
- docs/KIND_SETUP.md: Detailed KIND setup documentation
- docs/PROGRESS.md: Updated with KIND cluster completion

Console Services Access:
- Frontend: http://localhost:3000 (NodePort 30080)
- Backend: http://localhost:8000 (NodePort 30081)
