feat: 암호화모듈 프레임워크 신규 구현
- CryptoModuleExtension 인터페이스: BC 프로바이더, AAD, 편의 메서드 오버로드 추가 - AESCryptoModuleExtension: CBC/GCM/ECB/FF1 지원, GCM 랜덤 nonce, AAD 처리 - ARIACryptoModuleExtension: ARIA 알고리즘 지원 - CryptoModuleConfigVO: JPA Entity 분리를 위한 Lombok VO - CryptoModuleManager: VO 패턴 적용, FQCN 기반 전략 동적 로딩(Class.forName) - CryptoModuleService: STATIC/DYNAMIC × AAD 조합 8가지 오버로드 - CryptoModuleConfigMapper: MapStruct Entity→VO 매퍼 - KeyDerivationStrategy 인터페이스 및 DerivedKey - HsmContextXorKeyDerivationStrategy: HSM 마스터키 XOR 컨텍스트값 전략 - ReloadCryptoModuleCommand: 설정 런타임 재로드 커맨드 - build.gradle: BouncyCastle bcprov-jdk15on:1.70 의존성 추가 - 단위 테스트 전체 추가 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
