feat: ESPI 4.0 Schema Compliance - Phase 13: RetailCustomer (#80)

* feat: ESPI 4.0 Schema Compliance - Phase 13: RetailCustomer (#80)

Convert RetailCustomerEntity from IdentifiedObject to Object pattern since it
is an application-specific correlation table, not part of ESPI standard.

## Changes
- **Entity**: Changed RetailCustomerEntity from IdentifiedObject to Object
  - Removed IdentifiedObject inheritance (UUID ID, created, updated, published, links)
  - Changed ID from UUID to Long with auto-generated sequence
  - Removed description field (not needed for application table)
  - Removed merge(), updatePasswordDuringMerge(), getSelfHref(), getUpHref() methods
  - Updated toString() to remove IdentifiedObject fields

- **DTO/Mapper**: Deleted RetailCustomerDto and RetailCustomerMapper
  - Not needed since RetailCustomer is not an ESPI resource (no XML marshalling)

- **Repository**: Updated RetailCustomerRepository
  - Changed JpaRepository<RetailCustomerEntity, UUID> to JpaRepository<RetailCustomerEntity, Long>
  - Removed redundant @query annotations (let Spring Data generate queries)
  - Changed findLockedAccounts() to findByAccountLockedTrue()
  - Kept @query only for findAllIds() (performance optimization)
  - Changed return types from UUID to Long

- **Service**: Simplified RetailCustomerService
  - Removed methods: findByHashedId, add, delete, importResource, associateByUUID
  - Changed findById parameter from UUID to Long
  - Kept only essential methods: findAll, findById, save, findByUsername
  - Removed dependencies on RetailCustomerMapper

- **Database Migrations**:
  - Moved retail_customers table from V1 to vendor-specific V2 files (auto-increment syntax)
  - Added retail_customers with BIGINT AUTO_INCREMENT (H2/MySQL) and BIGSERIAL (PostgreSQL)
  - Kept only username index (authentication hot path)
  - Changed retail_customer_id columns from CHAR(36) to BIGINT in:
    - authorizations table (V1)
    - subscriptions table (V1)
    - usage_points table (V2)
  - Added FK constraints in V2 after retail_customers is created:
    - ALTER TABLE authorizations ADD CONSTRAINT fk_authorization_retail_customer
    - ALTER TABLE subscriptions ADD CONSTRAINT fk_subscription_retail_customer
    - ALTER TABLE usage_points ADD CONSTRAINT fk_usage_point_retail_customer

- **Related Entity Updates**:
  - AuthorizationRepository: Changed findAllByRetailCustomerId(UUID) to (Long)
  - AuthorizationService: Updated all methods accepting retailCustomerId to use Long
  - UsagePointEntity: Changed getUpHref() to use retailCustomer.getId() instead of getHashedId()
  - UsagePointRepository: Changed findAllByRetailCustomerId(UUID) to (Long)
  - UsagePointService: Updated all methods accepting retailCustomerId to use Long
  - SubscriptionService: Changed findRetailCustomerId() return type from UUID to Long
  - SubscriptionRepository: Changed findByRetailCustomerId(UUID) to (Long)
  - ElectricPowerQualitySummaryRepository: Changed xpath methods to accept Long for o1Id
  - UsageSummaryRepository: Changed xpath methods to accept Long for o1Id

- **Tests**: Updated all tests to use Long instead of UUID for retail_customer_id
  - RetailCustomerRepositoryTest: Updated for Long ID, removed IdentifiedObject tests
  - TestDataBuilders: Removed setDescription() for RetailCustomer
  - AuthorizationRepositoryTest: Changed UUID.randomUUID() to 999999L
  - UsagePointRepositoryTest: Changed UUID.randomUUID() to 999999L
  - SubscriptionRepositoryTest: Changed UUID.randomUUID() to 999999L
  - ElectricPowerQualitySummaryRepositoryTest: Updated for Long retailCustomerId
  - UsageSummaryRepositoryTest: Updated for Long retailCustomerId

## Test Results
All 532 tests pass successfully including integration tests with H2, MySQL, and PostgreSQL.

* fix: Update datacustodian controllers for RetailCustomer Long ID type

Fix compilation errors in openespi-datacustodian module after Phase 13
RetailCustomer entity conversion from UUID to Long ID:

- RetailCustomerController.java:
  * Change @PathVariable from UUID to Long in show() method
  * Remove unused UUID import

- AssociateUsagePointController.java:
  * Change @PathVariable from UUID to Long in form() and create() methods
  * Comment out associateByUUID() call (method removed in Phase 13)
  * Update commented code to use associateById() with Long type
  * Keep UUID import (still used by validator)

Resolves CI/CD build failures in PR #80.

* fix: Update thirdparty test files for RetailCustomer Long ID type

Update test files to use Long instead of UUID for retailCustomerId:

- UsagePointRESTRepositoryIntegrationTest.java:
  * Line 85: Change mock from any(UUID.class) to any(Long.class)
  * Line 121: Change UUID.randomUUID() to 1000001L
  * Line 133: Change UUID.randomUUID() to 1000004L

- MeterReadingRESTRepositoryImplTests.java:
  * Line 46: Change UUID retailCustomerId to Long (1000002L)

- MeterReadingServiceImplTests.java:
  * Line 50: Change UUID retailCustomerId to Long (1000003L)

All thirdparty tests pass: 47 tests run, 0 failures, 0 errors.
