style(web): 侧栏仅保留模块菜单并补图标；内容区统一 Card wrapper 与页面背景区分

- 侧栏 menuHeaderRender=false，折叠菜单只剩模块链接（标题由 TopNav 呈现）
- 菜单补齐 10 个常用语义图标（账号导入/我的账号/监控账号/竞品分析/工作台/采集设置/任务中心/运行环境/网络出口/网关管理）
- 列表与详情/新建/编辑页主内容统一 <Card variant=outlined> 包裹，对齐 pro 官方预览的灰底+白卡层次（17 处）
- metadata.ts → metadata.tsx（菜单 icon 需 JSX）；ScanEyeOutlined/ChatSettingsOutlined 在当前 @ant-design/icons 不存在，改用 EyeOutlined/CommentOutlined
