Move IdentifiedObject to common domain package

ARCHITECTURAL IMPROVEMENT:
- Move IdentifiedObject from usage domain to common domain package
- Fixes inappropriate dependency: Customer domain → Usage domain
- Establishes proper shared base class location

CHANGES:
✅ Created: src/main/java/org/greenbuttonalliance/espi/common/domain/common/IdentifiedObject.java
✅ Updated: All Customer domain imports to use common.IdentifiedObject
✅ Updated: All Usage domain imports to use common.IdentifiedObject
✅ Updated: BaseMapperUtils import to use common.IdentifiedObject
✅ Removed: Old IdentifiedObject from usage domain

ARCHITECTURAL BENEFITS:
- Clean domain separation maintained
- No circular dependencies between Customer ↔ Usage domains
- Shared base class properly located in common package
- Preserves PII-compliant domain boundaries

This resolves the dependency issue while maintaining the excellent
privacy-by-design separation between Customer (PII) and Usage (PII-free) domains.
