Make Entire "Add a Message for the Restaurant" Button Clickable in the Cart

Is your feature request related to a problem? Please describe.
In the Enatega app (Cart section), the "Add a message for the restaurant" button should be fully clickable, not just the arrow icon. This enhancement would make the entire button area responsive, improving user experience and accessibility.

Describe the solution you'd like

Currently, only the arrow icon next to the "Add a message for the restaurant" option is clickable.
The entire button, including the text and arrow, should be clickable, allowing users to easily add a message for the restaurant when reviewing their cart.
This change would ensure a smoother, more intuitive interaction, reducing the chances of misclicking and improving the overall user experience.

检查 Enatega 应用的 Cart 部分，并找到附加到“Add a message for the restaurant.”旁边箭头上的现有点击处理程序。让整个按钮区域（包括文本和箭头）触发相同的操作。当用户点击按钮区域中的任意位置都可以打开餐厅消息流程时，即表示完成。
