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
