Resolve port conflicts in masterdata-service: update application.yml with separated bind addresses (Spring: 127.0.0.1, Ktor: 0.0.0.0), change management port to 8086, and add explicit datasource and Flyway configuration. Fix startup issues with Database.connect() in MasterdataDatabaseConfiguration.
