style(business-crud-page): 优化运单详情起终点区域样式

- 将起终点区域改为垂直时间轴风格，左侧显示两个圆点，右侧显示详细地址及省市区信息
- 删除旧的起终点样式类，确认无其他引用，保证代码清晰
- 实现响应式设计，窄屏时垂直时间轴自动变为整行展示

style(master-order-editor): 调整多联总单编辑页收发货信息布局

- 修复竖向时间轴节点图标被压扁问题，增加最小宽高和防止缩小样式
- 优化收发货信息输入区网格布局，地址项独占前两列，宽度加大，支持长地址显示
- 响应式下地址项独占整行，保证小屏幕下不被截断
- 修改搜索栏白底样式，让选择常用地址弹窗搜索栏也使用白底，保持视觉一致性
