Refactor Integration Test with DigitalTwinPartApiSupport

Summary

This Pull Request introduces a new support class DigitalTwinPartApiSupport to handle all REST interactions related to /digitalTwinPart endpoints.
It improves test maintainability, reduces duplication, and aligns with the established testing architecture (e.g., AssetsApiSupport).

Goal

• Extract REST call logic from DigitalTwinPartsControllerIT
• Encapsulate interactions in a reusable DigitalTwinPartApiSupport class
• Support flexible validation of status codes and response body extraction
• Improve test readability and structure

What's Included

Added

• DigitalTwinPartApiSupport.java under integration/common/support
  • Endpoints covered:
    • POST /api/administration/digitalTwinPart
    • POST /api/administration/digitalTwinPart/detail
    • POST /api/administration/digitalTwinPart/searchable-values
  • Features:
    • JWT-based authorization using JwtRole.ADMIN
    • expectedStatusCode parameter for validation
    • Generic response deserialization with TypeRef<T> / Class<T>
    • Internal exception handling for JoseException

Refactored

• All test methods in DigitalTwinPartsControllerIT now use DigitalTwinPartApiSupport
• Direct RestAssured calls removed from the test class

New Test Added

• shouldReturnSearchableValuesForFieldName()
  • Verifies functionality of /searchable-values endpoint
  • Fully based on the refactored structure

Design Notes

• Pattern and structure inspired by AssetsApiSupport
• Used @Component and @RequiredArgsConstructor for clean DI
• Logs retained for request/response debugging (.log().all())
• Exception-safety provided by wrapping JoseException in RuntimeException

Acceptance Criteria Met

• Support class exists in correct package
• All /digitalTwinPart* calls extracted to support class
• Methods validate status code and return full response
• All tests pass and logic remains intact
• One new test using support class added
• Code reviewed and follows existing architectural standards
