Dispatch Page Search Box Only Works with Order ID

Describe the bug
The search box on the "Dispatch" page only returns results when an order ID is entered. It does not work with any other relevant search terms such as restaurant name, customer name, or contact number, making it difficult to quickly locate orders using other identifying information.

To Reproduce
Steps to reproduce the behavior:

Go to the "Dispatch" page.
Enter a restaurant name, customer name, or phone number in the search box.
Observe that no results are returned.
Enter an order ID and observe that results appear.
Expected behavior
The search functionality should support multiple fields such as restaurant name, customer name, and contact number in addition to order ID, to improve order lookup efficiency.

Additional context
This limitation significantly reduces the usability of the Dispatch page, especially for support and operations teams handling high volumes of orders.

从 Dispatch 页面开始，跟踪搜索框的实现，然后使用订单 ID、餐厅名称、客户名称和联系电话重现该问题。更新搜索行为，使所有列出的识别字段都能返回匹配的订单，并验证按订单 ID 搜索仍然有效。
