feat: 新增二级菜单子导航系统（SubNav + redirectMenu）

- 新增 SubNav 组件：Navbar 下方水平子导航条，展示当前二级菜单下的三级页面，支持滚动和下拉分组 - 新增 redirectMenu 页面：点击二级菜单时卡片式展示子页面列表 - SidebarItem 深度 >=1 时改为叶子节点渲染（小圆点标记），激活高亮回退到二级菜单 - Navbar 布局重构为 Flexbox，面包屑/SubNav 根据场景切换 - 新增 productionLine Vuex 模块，轧辊研磨页改为 store 方式读取产线数据 - Sidebar activeMenu 逻辑增强：自动定位当前页所属二级菜单
