Subject: [PATCH] feat: ESPI 4.0 Schema Compliance - Phase 0.4: Usage Domain
 Enums Batch 3

Implements third batch of ESPI usage domain enumerations from espi.xsd:
- ItemKind (10 values) - Billing line item classifications
- ServiceKind (10 values) - Service types at UsagePoint
- UnitSymbolKind (124 values) - Base units of measure

All enums include:
- Apache License 2.0 header (copyright 2025 Green Button Alliance, Inc.)
- JAXB/Jakarta XML binding annotations (@XmlType, @XmlEnum, @XmlEnumValue)
- getValue() and fromValue(int) methods
- Comprehensive Javadoc from XSD documentation with line numbers
- Type-safe enum constants with integer values

Total enum values in batch: 144
Per ESPI 4.0 specification (NAESB REQ.21)

Unit tests: 638/638 passed

Related to #101
