feat(schema): 데이터베이스 스키마 강화 마이그레이션
데이터 무결성: - user_deposits.balance >= 0 CHECK 제약조건 - deposit_transactions.depositor_name 최대 50자 제한 - 음수 잔액 방지, 긴 이름 방지 감사 추적: - audit_logs 테이블 생성 - 모든 중요 작업 추적 (user_id, action, resource, details) - 인덱스 추가 (user_id, action, created_at) 프로덕션 안전: - 백업 → 재생성 → 복원 방식 - 롤백 스크립트 포함 - 데이터 유실 방지 로직 - 음수 잔액 데이터 감지 및 로그 마이그레이션 파일: - migrations/001_schema_enhancements.sql (5.5K) - migrations/001_rollback.sql (4.0K) - migrations/AUDIT_LOG_EXAMPLES.ts (11K) - migrations/TEST_RESULTS.md (8.0K) - migrations/README.md (2.8K) 문서: - SCHEMA_MIGRATION_GUIDE.md (13K) - 완전한 배포 가이드 - MIGRATION_SUMMARY.md (9.1K) - 요약 및 체크리스트 로컬 테스트 결과: - ✅ 마이그레이션 성공 (23 commands, <1초) - ✅ CHECK 제약조건 작동 (음수 잔액 거부) - ✅ 길이 제한 작동 (51자 이름 거부) - ✅ audit_logs 테이블 정상 - ✅ 데이터 보존 확인 (users:3, deposits:1, transactions:1) - ✅ 음수 잔액 데이터 감지 (user_id:3, balance:-500) 프로덕션 배포: - 로컬 테스트 완료, 프로덕션 준비 완료 - 배포 전 백업 필수 - 예상 소요 시간: <5분 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

-- Migration 001: Schema Enhancements
|

-- Purpose: Add data integrity constraints and audit logging

-- STEP 1: user_deposits - Add CHECK constraint for balance >= 0
|

-- =============================================================================

-- 1.1 Create backup table
