🛡️ Sentinel: [HIGH] Fix CPU exhaustion DoS vulnerability in password hashing

[seonghobae]

🚨 Severity: HIGH
💡 Vulnerability: 사용자 비밀번호 입력값에 최대 길이 제한이 없어, 매우 긴 문자열을 전송할 경우 bcrypt 해싱 과정에서 과도한 CPU 자원이 소모되는 DoS(서비스 거부) 취약점이 존재했습니다.
🎯 Impact: 공격자가 악의적으로 거대한 비밀번호 문자열을 회원가입, 로그인 또는 비밀번호 재설정 엔드포인트에 지속적으로 전송할 경우, 서버의 CPU 자원이 고갈되어 정상적인 서비스 제공이 불가능해질 수 있습니다.
🔧 Fix: @argos/shared의 LoginRequestSchema, RegisterRequestSchema 및 @argos/web의 ResetPasswordSchema 내 password와 passwordConfirmation 필드에 .max(1024) 검증 로직을 추가하여 입력값의 크기를 안전한 수준으로 제한했습니다.
✅ Verification: pnpm test 명령어를 통해 인증 관련 테스트(예: auth-flow.test.ts, password-reset-links/route.test.ts 등)가 모두 정상적으로 통과함을 확인했습니다. (No regressions)
