Adds CronJobs and headless driver Services for GameLengthJob, ColorAdvantageJob,
EloDistributionJob, TimeControlJob, DailyActivityJob, RatingMismatchJob, and
TerminationStatsJob. All suspended by default; scheduled Saturday mornings.
Adds spark-analytics-webview: a stdlib Python HTTP server (ConfigMap + Deployment
+ Service) that reads CSV output from the spark-analytics-output PVC and renders
13 datasets as browsable HTML tables. Disabled (replicas=0) in base.
Staging overlay enables the webview (replicas=1), exposes it via Ingress at
spark-results-st.nowchess.janis-eccarius.de, and sets NOWCHESS_PGN_PATH on all
CronJobs to the Lichess Jan-2013 rated standard PGN dump for demo runs without
a NowChess database.

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
