[Am0du]

Description: Implement the following CRUD (Create, Read, Update, Delete) operations for managing products within an organization:

1. Create a Product

   • Endpoint: POST /organisation/{org_id}/products
   • Description: Allows an admin user to create a product under a specific organization.
   • Pre-Authorization: Admin role required.

2. Delete a Product

   • Endpoint: DELETE /products/{product_id}
   • Description: Allows an admin user to delete a product by its ID.
   • Pre-Authorization: Admin role required.

3. Edit a Product

   • Endpoint: PUT /products
   • Description: Allows an admin user to edit an existing product.
   • Pre-Authorization: Admin role required.

Acceptance Criteria:

• [ ] The POST /organisation/{org_id}/products endpoint creates a product under the specified organization.
• [ ] The DELETE /products/{product_id} endpoint deletes the specified product.
• [ ] The PUT /products endpoint updates the specified product with new data.
• [ ] Each endpoint should check if the authenticated user belongs to the organization and has the required role.
• [ ] Appropriate HTTP status codes should be returned (201 for creation, 204 for deletion, 200 for updates).
• [ ] Proper exception handling should be implemented for cases such as unauthorized access or resource not found.

Error Handling:

• Unauthorized access should throw an UnAuthorizedException with a 403 status code.
• Product not found should throw a NotFoundException with a 404 status code.
