feat(domain,events): bitemporal entities + i18n-aware definitions + sealed event API

ordinis-domain:
- DataScope enum (PUBLIC/INTERNAL/RESTRICTED) с Kafka topic suffix + visibility logic
- DictionaryDefinition entity: scope, schema_json (JsonNode JSONB), schema_version,
  bundle, supported_locales (text[]), default_locale + Spring Data Auditing
- DictionaryRecord entity: bitemporal (Envers tx-time + valid_from/valid_to),
  data JSONB, geometry (JTS via hibernate-spatial), data_scope. EXCLUSION
  CONSTRAINT enforced в БД (Liquibase 0003).
- AuditLog entity для compliance (отдельно от Loki)
- OutboxEvent entity: aggregate_*, kafka_topic/kafka_key, attempt_count,
  markPublished/markFailed, partial index idx_outbox_unpublished
- IdempotencyKey entity для exactly-once семантики write API
- Repositories: findActiveAt, findActiveByDictionaryAndScopes, findUnpublished
- JpaAuditingConfig: ConditionalOnBean(DataSource) — dev profile без БД
  не активирует auditing, metamodel не строится

ordinis-events-api:
- Mirror DataScope enum (events не depend on domain)
- EventEnvelope<T> record: eventId, occurredAt, schemaVersion (semver),
  bundle, dictionaryName, scope, traceId, spanId, payload
- Sealed DictionaryRecordEvent + records Created/Updated/Deleted
- Sealed DictionaryDefinitionEvent + records Created/Updated
- Jackson polymorphism через @JsonTypeInfo discriminator
- Multi-locale payload: события возят ВСЕ локали (consumer сам сплющивает)

i18n design:
- В JSONB поле кодируется как { 'ru-RU': '...', 'en-US': '...' }
- JSON Schema справочника помечает локализуемые поля extension x-localized:true
- supported_locales + default_locale в dictionary_definitions
- Read API будет negotiate через Accept-Language (RFC 7231) и сплющивать

Validation:
- mvn install all 11 modules: BUILD SUCCESS
- ordinis-app boot dev profile: /actuator/health UP, / отвечает
