Add DeliveryAddress DTO and update references in authentication classes

[NourAlPha]

This pull request introduces a new DeliveryAddress DTO to the com.podzilla.auth.dto package and updates references across the codebase to use this new class instead of the previously imported DeliveryAddress from com.podzilla.mq.events. The changes improve modularity by consolidating the DeliveryAddress class within the authentication module.

Introduction of DeliveryAddress DTO:

• Added a new DeliveryAddress class in the com.podzilla.auth.dto package. This class includes fields for street, city, state, country, and postalCode, all annotated with @NotBlank for validation. It implements Serializable and uses Lombok annotations for boilerplate code reduction.

Updates to DTOs:

• Removed imports of com.podzilla.mq.events.DeliveryAddress in SignupRequest, UpdateRequest, and UserDetailsRequest DTOs, as they no longer rely on the external DeliveryAddress class. [1] [2] [3]

Updates to Services:

• Updated UserService to use the new DeliveryAddress DTO from com.podzilla.auth.dto, replacing the previous import from com.podzilla.mq.events. [1] [2]

Updates to Tests:

• Updated test files AuthenticationControllerTest and AuthenticationServiceTest to import and use the new DeliveryAddress DTO from com.podzilla.auth.dto. [1] [2]
