Use Eventuate starters for auto-configuration

Replace explicit Eventuate configuration imports with Spring Boot
starters that provide auto-configuration:

- eventuate-tram-sagas-spring-orchestration-simple-dsl-starter
- eventuate-tram-sagas-spring-participant-starter

Remove redundant explicit imports now handled by auto-configuration:
- TramEventsPublisherConfiguration
- SagaOrchestratorConfiguration
- SagaParticipantConfiguration
- TramEventSubscriberConfiguration
- TramJdbcKafkaConfiguration
