Feat: Vendor should be able to get own products

[wayneleon1]

Description

Implement functionality to allow vendors to retrieve their own products on the backend side of the application. This feature will enable vendors to view a list of their products, including all details of product.

Requirements

1. Endpoint Creation:

   • Create a new API endpoint to fetch products belonging to a specific vendor.

2. Authentication & Authorization:

   • Ensure that the vendor is authenticated before they can access their products.
   • Implement authorization to ensure that a vendor can only access their own products and not those of other vendors.

3. Database Query:

   • Write a query to fetch products from the database that belong to the authenticated vendor.

Acceptance Criteria

• An authenticated vendor can successfully retrieve a list of their own products via the new API endpoint.
• The response includes all required product details in a structured JSON format.
• Appropriate error handling is in place for various failure scenarios.
• Unit tests are written to cover the new functionality.

Additional Notes

• Ensure the code follows existing code standards and practices.
• Provide documentation for the new API endpoint, including request and response examples.
• Collaborate with the frontend team to ensure they have the necessary information to integrate this new functionality.
