Subject: [PATCH] =?UTF-8?q?Kafka=20=EB=A9=94=EC=8B=9C=EC=A7=80=20=ED=83=80?=
 =?UTF-8?q?=EC=9E=85=20=EB=B6=88=EC=9D=BC=EC=B9=98=20=EC=88=98=EC=A0=95=20?=

변경 내역:
- EventCreatedMessage: eventId, userId 타입을 Long에서 UUID로 변경
- EventKafkaProducer: publishEventCreated 메소드 파라미터 타입을 UUID로 변경

변경 이유:
- Event Entity는 UUID 타입을 사용하지만 Kafka 메시지는 Long을 사용하여 타입 불일치 발생
- Entity와 Kafka 메시지 간 타입 일관성 확보
- 런타임 타입 변환 오류 방지

영향:
- Event Service 내부 일관성 확보
- 향후 타 서비스와의 통합 시 UUID 표준 준비
