feat(nci): add Spark analytics Kubernetes manifests
Wire five Spark jobs (OpeningBook, PlayerStats, PlayerClustering, PlayerGraph, LiveDashboard) to Kubernetes via native Spark-on-K8s mode. - spark-analytics/base: ServiceAccount, RBAC Role/RoleBinding (driver executor pod management), two PVCs (10Gi output, 2Gi checkpoint), four CronJobs for batch analytics, one Deployment for the Structured Streaming live dashboard - spark-analytics/eu-central-1-prod: namespace overlay pinning image to 0.1.0 with strategic merge patches that update both the container image field and the spark.kubernetes.container.image conf arg - eu-central-1/argo-apps/spark-analytics: ArgoCD Application pointing at the prod overlay with automated prune+selfHeal sync Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
