[Hibernate 7] refresh/lock of a detached entity fails 'Given entity is not associated with the persistence context' (DetachedObjectException) — hibernate.allow_refresh_detached_entity removed

Cause (Documented platform behavior): Jakarta Persistence requires IllegalArgumentException for refreshing detached entities; Hibernate 7 aligned and removed the legacy hibernate.allow_refresh_detached_entity setting. Fix status: documented_behavior Limitations: - Exact exception subclass may be translated to IllegalArgumentException at the JPA boundary.
