refactor: Phase 7 - ServiceDeliveryPoint ESPI 4.0 schema compliance

[dfcoffin]

Summary

Phase 7 of Issue #28: Aligns ServiceDeliveryPoint DTO, mapper, and repository with ESPI 4.0 XSD specification.

Key Finding: Per ESPI 4.0 specification (espi.xsd), ServiceDeliveryPoint extends Object (not IdentifiedObject), so it has NO id/uuid/mRID fields or Atom metadata.

Changes Made

DTO Updates (ServiceDeliveryPointDto)

• ✅ Removed Long id and String uuid fields (Object type has no mRID attribute)
• ✅ Updated @XmlType propOrder to match XSD element sequence: name → tariffProfile → customerAgreement → tariffRiderRefs
• ✅ Removed redundant canonical constructor (Java records auto-generate it)
• ✅ Updated helper methods to reflect no uuid field

Mapper Updates (ServiceDeliveryPointMapper)

• ✅ Removed @Mapping for id and uuid (fields no longer exist in DTO)
• ✅ Added explicit mappings for all XSD elements (name, tariffProfile, customerAgreement)
• ✅ Kept tariffRiderRefs as ignore = true (XML-only field, not persisted in entity)
• ✅ Removed updateEntity() method (read-only operations only)
• ✅ Removed unused import MappingTarget

Repository Updates (ServiceDeliveryPointRepository)

• ✅ Kept only indexed query: findAllIds()
• ✅ Removed 5 non-indexed custom queries: findByName, findByTariffProfile, findByCustomerAgreement, findByNameContaining, countByTariffProfile
• ✅ Removed custom deleteById override (JpaRepository provides it)
• ✅ Removed unused imports

Test Updates (ServiceDeliveryPointRepositoryTest)

• ✅ Removed 5 test methods for deleted repository queries
• ✅ Kept findAllIds() test (indexed query retained)
• ✅ All 23 remaining tests pass successfully

Verification

Entity Verification

✅ ServiceDeliveryPointEntity structure already matches XSD correctly:

• Uses Long id (BIGINT primary key)
• Has name, tariffProfile, customerAgreement fields (all String256)
• Does NOT extend IdentifiedObject (correct per XSD)

Database Verification

✅ Flyway migrations verified in all vendor-specific V2 scripts:

• db/vendor/mysql/V2__MySQL_Specific_Tables.sql
• db/vendor/postgres/V2__PostgreSQL_Specific_Tables.sql
• db/vendor/h2/V2__H2_Specific_Tables.sql

All scripts create service_delivery_points table with correct structure and indexes.

Test Results

Tests run: 536, Failures: 0, Errors: 0, Skipped: 0

✅ All tests pass (ServiceDeliveryPointRepositoryTest: 23 tests)
✅ MySQL TestContainer integration tests pass
✅ H2 integration tests pass

Technical Notes

XSD Compliance

Per espi.xsd line ~1161:

<xs:complexType name="ServiceDeliveryPoint">
  <xs:complexContent>
    <xs:extension base="Object">
      <xs:sequence>
        <xs:element name="name" type="String256" minOccurs="0"/>
        <xs:element name="tariffProfile" type="String256" minOccurs="0"/>
        <xs:element name="customerAgreement" type="String256" minOccurs="0"/>
        <xs:element name="tariffRiderRefs" type="TariffRiderRefs" minOccurs="0"/>
      </xs:sequence>
    </xs:extension>
  </xs:complexContent>
</xs:complexType>

Object base type has NO mRID attribute (unlike IdentifiedObject which has mRID). This is consistent with other Object-based types like IntervalReading and ReadingQuality.

Repository Query Removal Rationale

Removed non-indexed queries following read-only CRUD pattern from Phases 5-6:

• Applications only support read operations via indexed lookups
• Custom queries like findByName, findByTariffProfile etc. were not indexed and not used
• Kept findAllIds() as it provides indexed bulk ID retrieval

Testing Checklist

• Unit tests pass (23/23 ServiceDeliveryPoint tests)
• Integration tests pass (MySQL TestContainer)
• Integration tests pass (H2)
• All 536 tests in openespi-common pass
• DTO field order matches XSD element sequence
• Entity structure verified against XSD
• Flyway migrations verified (all vendors)
• No compilation warnings for ServiceDeliveryPoint files
