PR Summary

• Enhanced User Comparison in Checkout Process
  The logic in handling checkout acceptances was refined in the application. Now, to further build robustness, the code reliably compares if an item checked out is indeed assigned to the appropriate user. This is done using advanced null-proof comparison techniques.

• Improved Testing for Accessory Acceptance Mechanism
  In order to ensure that our accessory acceptance process works as expected, we've introduced expanded testing capabilities that check if a user can accept an item that is not assigned to them. This test creates a hypothetical user and assigns an item to them, attempting to accept the item and expecting to receive an appropriate error message. This helps us ensure that items only get accepted by their rightful assignees, enhancing the overall security and integrity of our checkout system.
