feat(k8s): F7 集群详情EventsTab真实后端对接 + go vet修复

1. EventsTab.tsx: DEMO_EVENTS硬编码→kubernetesApi.getEvents真实K8s事件
   - 复用 normalizeK8sEvent/formatEventRelative 工具（与 EventsPage 一致）
   - 新增 loading/empty 状态 + 刷新按钮
   - Warning事件优先排序 + 限100条防溢出
   - KubernetesClusterDetail 传入 clusterCode prop
   - 修复 Q28 组件拆分时遗留的 demo 数据未对接缺口

2. aiops_alert_analysis.go: log.Printf %s→%d 修复 go vet 失败
   - AlertID 类型为 uint, %s 格式符不匹配致 go test 构建失败
   - go vet ./... 全量零错误

验证: tsc -b=0, npm build✓ (18.00s), go build=0, go vet=0, 17/17测试通过
Events API 返回5条真实事件 (type=Normal, reason=Pulled, count=5487)
