[UBS] Refactoring Address Management: Creating a Dedicated Service and Controller

[KizerovDmitriy]

Description:
To improve code maintainability, scalability, and separation of concerns, the address management logic should be refactored into a dedicated service. Currently, address-related operations are handled within existing services, making the codebase more complex and harder to maintain.

Scope of Work:

• Extract all address-related logic into a separate AddressService.
• Develop a new AddressController to handle address-specific operations via dedicated endpoints.
• Ensure that other services interact with addresses through the new service instead of handling address logic directly.
• Refactor existing code to integrate the new service properly.
• Implement necessary unit and integration tests to verify the functionality of the new structure.
• This refactoring will enhance system modularity, simplify future enhancements, and improve overall maintainability.
