Refactor Customer domain for NAESB ESPI 4.0 compliance
Major architectural changes to Customer domain classes: CONVERTED TO @MappedSuperclass (Abstract base classes): - Agreement: Extends Document → IdentifiedObject - Asset: Extends IdentifiedObject - AssetContainer: Extends Asset → IdentifiedObject - Document: Extends IdentifiedObject - Location: Extends IdentifiedObject - WorkLocation: Extends Location → IdentifiedObject CONVERTED TO @embeddable (Component classes): - Organisation: Pure component with embedded StreetAddress, PhoneNumber, ElectronicAddress - OrganisationRole: Contains embedded Organisation - AccountNotification: Pure component for notifications UPDATED @entity classes: - CustomerEntity: Now extends IdentifiedObject with embedded Organisation - CustomerAccountEntity: Extends Document → IdentifiedObject - CustomerAgreementEntity: Extends Agreement → Document → IdentifiedObject - ServiceLocationEntity: Extends WorkLocation → Location → IdentifiedObject - ServiceSupplierEntity: Extends IdentifiedObject with embedded Organisation COMPLIANCE ACHIEVEMENTS: ✅ Proper separation of concerns between entities, components, and abstractions ✅ All @entity classes extend IdentifiedObject for UUID primary key support ✅ All @MappedSuperclass files have proper @column JPA annotations ✅ All @embeddable files have proper @Column/@Embedded JPA annotations ✅ NAESB ESPI 4.0 compliant domain model structure ✅ Service layer updated for new entity names and relationships 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
