fix(waybill-manage): 修复运单详情弹窗残留问题

- 页面形态状态（列表/独立表单页/独立详情页）在实例创建时锁定，避免随路由变化切换导致弹窗残留
- 模板中形态相关所有判定改为使用锁定状态变量，保证渲染一致性
- 修改 detailContainer、crudContainer、pageFormOption 等方法使用锁定状态，避免缓存实例 option 变形
- 新增 closeInnerDialogs 方法，在组件 deactivated 和 beforeUnmount 生命周期关闭所有 append-to-body 弹窗
- 解决标签页 keep-alive 机制下弹窗 Teleport 持续遗留导致界面异常的问题
- 对运单管理页面多处弹窗和视图控制做统一修复，提升页面稳定性和体验
