Wires the Postgres LISTEN/NOTIFY ClusterEventBus default.

Ordered before OnecAutoConfiguration so its @ConditionalOnMissingBean bus registers ahead of that module's no-op fallback. It contributes a bus only when the PostgreSQL JDBC driver is present and the live datasource is actually Postgres (detected via SqlDialect); on H2 (dev/test) it returns a NoOpClusterEventBus, so the framework's single-node behaviour is preserved. An application's own ClusterEventBus bean (e.g. Kafka/Redis) wins over both via @ConditionalOnMissingBean.
