fix(k8s): 修复 shared-components.tsx JSX 结构错误致前端构建失败 + 补全残余 i18n 硬编码中文

- fix: shared-components.tsx ContainerInfo 端口区块多余 <div> 标签致 JSX 闭合错误 (TS17008)
- i18n: EventsPage/DeploymentDetail/DeploymentEditAdvanced/Containers/Storage 等 K8s 组件残余硬编码中文→t() 调用
- i18n: zh/en 7987 键完全对齐, 新增 k8s.eventsPage/k8s.workload 等语义化键
- tsc -b=0, npm build✓ (17.48s), ESLint errors=0/warnings=43/any=0, go build=0
- 17/17 集成测试通过, Docker 部署 healthy
