Subject: [PATCH] Implement Logout functionality

<UserStory> CUS002: Logout</UserStory>

<Changes>
    1. Connected Controller::logout() with AuthenticationManagementService logout logic.
    2. Added logout implementation in AuthenticationManagementService to clear the authenticated user session.
    3. Added logout handling in CustomerMenu to invoke controller logout when the user selects the logout option.
    4. Added authentication service dependency in Controller for logout support.
</Changes>

<Test>

Logout functionality validation

Precondition:
1. System is running.
2. A registered user exists in the data store.
3. User is logged in and customer menu is active.

Steps:
1. Launch the application and log in with valid credentials.
   - Verify that access is granted and customer menu is displayed.
2. Select the Logout option from the customer menu.
   - Verify that the logout operation is triggered immediately.
3. Complete the logout operation.
   - Verify that the authenticated user session is cleared.
4. After logout completes.
   - Verify that the user is redirected to the login menu.

</Test>
