## Title

    [Hibernate 7] AnnotationException "'AttributeConverter' not allowed for attribute '<name>' annotated '@jakarta.persistence.Id' (use '@Convert(disableConversion=true)' to suppress this error)" — conve…

## Body

    Cause (Documented platform behavior): Hibernate 7 validates the model more strictly; incompatible converters now error instead of being ignored.
    
    Fix status: documented_behavior
    
    Other error fragments:
    -  (use '@Convert(disableConversion=true)' to suppress this error)

    - https://raw.githubusercontent.com/hibernate/hibernate-orm/7.0/migration-guide.adoc (official_docs, 2025, documented_behavior): 7.0 Disallowed Converters: converters incompatible with @Id, @Version, @Enumerated, @Embedded, @Temporal and associations now reported as errors, including auto-applied ones; use @Convert(disableConversion=true).
