feat(atlas): Phase C — live CD/deploy state on stage 07

Stage 07 now shows the pod's own live deploy state — deployed image tag +
N/M replicas ready, green only when the rollout is fully ready — read from the
k8s Deployment in-cluster (new namespaced deployments-read Role). DeployState/
DeployNode test-first; prepended to the authored CD narrative, fallback-safe.

Verified: build/vet/lint(0)/test green.
