feat(phase-1.1): deploy temporal server in k8s

Temporal infrastructure deployment with: - PostgreSQL StatefulSet (event log + visibility) - 10Gi PVC, health checks, port 5432 - Elasticsearch StatefulSet (workflow search) - 20Gi PVC, health checks, port 9200 - Temporal Server StatefulSet (main service) - Frontend: 7233, Matching: 7235, History: 7234, Worker: 7239 - Headless + ClusterIP services - Auto-setup image: temporalio/auto-setup:1.20.0 - Temporal UI Deployment (web visualization) - Port 3000, connects to frontend:7233 - LoadBalancer service for access Components: - 00-namespace.yaml: dedicated temporal namespace - 01-postgres-statefulset.yaml: event log backend - 02-elasticsearch-statefulset.yaml: search visibility - 03-temporal-server-statefulset.yaml: server + services - 04-temporal-ui-deployment.yaml: web ui - kustomization.yaml: deployment automation - README.md: deployment + troubleshooting guide Health checks: liveness + readiness on all components Persistence: PVCs with dynamic provisioning Ports: 5432 (postgres), 9200 (es), 7233-7239 (temporal) Deploy: kubectl apply -k k8s/temporal/ Effort: 150 LOC (complete K8s manifests)
