Event-AI Kafka 통신 개선 및 타입 헤더 불일치 문제 해결

주요 변경사항:
- event-service KafkaConfig: JsonSerializer로 변경, 타입 헤더 비활성화
- ai-service application.yml: 타입 헤더 사용 안 함, 기본 타입 지정
- AIEventGenerationJobMessage: region, targetAudience, budget 필드 추가
- AiRecommendationRequest: region, targetAudience, budget 필드 추가
- AIJobKafkaProducer: 객체 직접 전송으로 변경 (이중 직렬화 문제 해결)
- AIJobKafkaConsumer: 양방향 통신 이슈로 비활성화 (.bak)
- EventService: Kafka producer 호출 시 새 필드 전달
