[NourAlPha]

This pull request includes updates to dependencies, introduces role-based access control for the PromoCodeController, and modifies the event publishing logic in the cart checkout process. It also updates related unit tests to reflect the changes in event naming.

Dependency Updates:

• Updated the podzilla-utils-lib dependency version from 1.1.11 to v1.1.13 in pom.xml to incorporate the latest features or fixes.

Role-Based Access Control:

• Added the @AllowedRoles({"ROLE_ADMIN"}) annotation to the PromoCodeController to enforce that only users with the ROLE_ADMIN role can access the admin promotional codes endpoint. [1] [2]

Event Publishing Logic:

• Changed the event name from ORDER_PLACED to CART_CHECKEDOUT in the CartService to better align with the cart checkout process.

Unit Test Updates:

• Updated all relevant test methods in CartServiceTest to use the new event name CART_CHECKEDOUT instead of ORDER_PLACED. This ensures consistency with the updated logic in CartService. [1] [2] [3] [4] [5]
