feat(subsystem): 子系统导航增加可展开子 Tab 与详情页

- AppSidebar: 统一入口组下子系统导航改为可展开列表，展示 6 个子系统子 Tab
- 每个子 Tab 带功能描述前缀（如 多集群发布平台 Wayne）便于用户定位
- 新建 SubsystemDetail.vue 统一详情模板（统计卡片 + 门户卡片 + 打开按钮）
- 新增路由 /subsystem/detail/:name
- subsystem API mock 数据补充 label、domain、category 字段
- SubsystemCard 概览卡片同步显示 label + name 格式
