feat(k8s): M2 Pod Metrics 详情页接入 — ListPods 注入 metrics

后端: - 新增 buildPodMetricsMap() 公共辅助函数，聚合多容器 CPU/Memory - ListPods / listPodsWithNS / ListPodsAllNS 三个 handler 全部注入 - PodSummary 增加 cpu_usage_m / mem_usage_mi 字段前端: - KubernetesWorkloads Pod 表格增加 CPU/内存列 - NamespaceResourcePage Pod 表格增加 CPU/内存列验证: - 17 个 Pod 全部返回真实 metrics (argocd/demo-jar) - curl /kubernetes-clusters/1/pods → cpu_usage_m='2m' mem_usage_mi='61Mi' 文档: - ROADMAP M1→done, M2→done, 验收标准全部勾选 - TDD_PLAN M2 通过标准补充 - PROJECT_EVALUATION P0 缺失项移除
