refactor(ocpp2): use enum values instead of string literals in variable registry

Replace all string literals that have corresponding TypeScript enums:
- OCPP20OperationalStatusEnumType for AvailabilityState defaultValue/enumeration
- OCPP20ChargingRateUnitEnumType for ChargingScheduleAllowedChargingRateUnit
  defaultValue, enumeration, and description
