- KycObservabilityService / KycObservabilityServiceImpl
Updated admin/investor controllers and related service/repository logic for more consistent lifecycle handling.
Improved exception handling (RestExceptionHandler, ValidationException) and aligned API error behavior.
Updated runtime/local config (application.yml, application-local.yml, docker-compose.yml, pom.xml).
Expanded and stabilized tests (AdminKycControllerWebSliceTest, service tests, test slice bootstrap classes).
