Implement coupon's functionalities

[wayneleon1]

Description:

We need to implement coupon functionalities on the frontend side of our project to allow vendors to create and manage coupons. This feature will enable vendors to offer discounts to their customers by generating and controlling coupon codes.

Acceptance Criteria:

• A form is provided for vendors to create new coupons, including fields for coupon code, discount type (percentage or fixed amount), discount value, expiration date, and usage limits.
• Vendors can view a list of their created coupons with details such as the code, discount type, discount value, expiration date, and usage status.
• Vendors can edit or delete existing coupons.
• The coupon management section is styled to match the overall design of the project using Tailwind CSS.
• The feature is responsive and performs well across different devices and screen sizes.

Additional Notes:

• Ensure that the Backend API endpoints for creating, updating, and deleting coupons are available and optimized.
• Ensure proper testing is conducted to validate the functionality and performance of the coupon management feature.
• Consider security implications, such as ensuring only authorized vendors can create and manage their coupons.
