feat: K8s→Kubernetes命名统一 + 工具安装bug修复 + 资源可视化编辑器

1. 工具安装bug修复 (P0 critical):
   - 根因: ToolConfigHandler.InstallTool的goroutine只打了日志，
     从未调用实际安装逻辑
   - 修复: 注入ToolInstaller到handler, 新增ForceInstall方法绕过sync.Once
   - 影响: 流水线工具配置页「安装」按钮现在能真正触发下载安装

2. K8s→Kubernetes命名统一:
   - Dashboard/Prometheus/AIOpsAssistant等8个文件12处用户可见文案
   - 内部变量名/文件名/API group保持不变

3. 资源可视化编辑器 (新增ResourceVisualEditor.tsx):
   - ConfigMap: 键值对表格编辑器(增删改)
   - Secret: 键值对编辑器(自动Base64编解码)
   - Service: 端口/类型/选择器可视化配置
   - Ingress: Host/Path路由规则可视化编辑
   - PVC: 存储大小/访问模式/StorageClass配置
   - 双模式: 可视化编辑 ↔ YAML编辑一键切换
   - NamespaceResourcePage: 所有资源类型添加编辑按钮入口
