feat(layout): 添加路由视图刷新功能

- 在 BasicLayout 中添加 viewKey 响应式变量用于控制 router-view 的重新挂载
- 监听自定义 'app:refresh-view' 事件实现页面刷新功能
- 修改 router-view 组件 key 值为 viewKey + '-' + r.fullPath 实现条件渲染

feat(tabs-nav): 优化标签页操作功能

- 添加 handleRefresh 方法通过 dispatchEvent 触发页面刷新事件
- 实现 handleCloseOthers、handleCloseRight、handleCloseAll 方法
- 优化 handleTabClick 避免重复点击当前路由
- 移除无用的激活状态小圆点和右键菜单注释代码

refactor(mock): 调整 mock 数据导入逻辑

- 将 import.meta.env.DEV 条件判断改为直接导入，简化代码结构
