test(rest): add ArchUnit tests for SW360

[bibhuti230185]

Summary

Add comprehensive ArchUnit architecture tests for the SW360 REST resource-server module. These tests enforce architectural patterns, coding standards, and best practices as defined in the SW360 backend instructions.

51 architecture rules across 12 test suites validate:

Test Suite	Tests	Purpose
Controller Annotation Rules	6	Validates REST controller annotations
Controller-Service Relationship Rules	3	Ensures proper controller-service patterns
Dependency Injection Rules	2	Enforces constructor injection over field injection
Layer Dependency Rules	3	Maintains layer separation
Logging Standard Rules	5	Enforces Log4j2 logging standards
Naming Convention Rules	5	Validates class naming patterns
OpenAPI Documentation Rules	2	Ensures OpenAPI documentation annotations
Package Structure Rules	5	Enforces package organization
Security Annotation Rules	4	Validates security annotations
Spring Framework Rules	7	Enforces Spring best practices
Thrift Service Boundary Rules	3	Prevents bypassing Thrift services
Coding Standard Rules	6	General coding standards

New Dependencies

• com.tngtech.archunit:archunit-junit5 (test scope) — added to rest/resource-server/pom.xml
• ArchUnit BOM 1.4.0 managed in root pom.xml

How To Test?

Run the ArchUnit test suite:

# Run all architecture tests
mvn test -pl rest/resource-server -Dtest="*RulesTest"

# Run a specific test suite
mvn test -pl rest/resource-server -Dtest="ControllerAnnotationRulesTest"

All 51 tests should pass. Any architectural violation will produce a descriptive failure message pointing to the offending class and method.
