First configuration

Most suites start by declaring a shared topic list in test properties. Move to a YAML or JSON topic file when topics need different partition counts.

src/test/resources/application.properties

wiretap.test.topics=orders,payments,notifications
wiretap.test.partitions=2

wiretap.test.topics=orders,payments,notifications
wiretap.test.partitions=2
