feat(nci-11): add Kubernetes manifests for nowchess-analysis service (#381)

Add Argo Rollout (blueGreen), active/preview Services, and HPA for the
new analysis service (port 8087). Wire image pins into all three overlay
kustomizations and register the analysis Warehouse and freight entries in
all three Kargo Stages (staging -> eu-central-1-prod / htwg-1-prod).
