improve modal style for discart changes

current card is too big : 

<img width="641" height="210" alt="Image" src="https://github.com/user-attachments/assets/8ec767da-951a-48ce-af26-39855fa9011c" />

we want it to have the same style as : 

<img width="491" height="291" alt="Image" src="https://github.com/user-attachments/assets/56f69275-ec50-44e0-9351-2483146912a6" />
