지수형 부동소수점 validation 정규화 flag 추가 (transformer.scientific.normalize)

- SystemKeys: TRANSFROMER_SCIENTIFIC_NORMALIZE 키 및
isScientificNormalizeEnabled() 추가
- JSONMessage.isValid(): flag ON 시 toPlainString()으로 정규화 후 검증
- false positive 방지: 1.23e5(=123000)가 자릿수 제한을 우회하는 문제 차단
- false negative 방지: pointLength=0 필드에서 유효한 지수형 값이 거부되는 문제 해결
- JSONMessageValidationTest: 지수형 시나리오 4개 추가 (정규화 ON/OFF 각 케이스)
