…nding and conditional beans Also fix nested PostgresStoreConfiguration to use proxyBeanMethods=false (Kotlin classes are final; CGLIB proxying requires non-final classes) and add assertj-core to version catalog (required by spring-boot-test's ApplicationContextRunner).
The enabled flag is handled by @ConditionalOnProperty on the bean factory. Having it also in the properties class was redundant — no code read it.

Summary
Makes OutboxPurger a production-ready, configurable component — establishing a pattern to replicate for OutboxScheduler/ProcessorScheduler.
