- 작업지시 관련 마이그레이션 파일명 날짜 수정 (의존성 순서 해결)
  - 2025_01_08 → 2025_12_26_100400 (tenant_id 추가)
  - 2025_01_09 → 2025_12_26_100600 (assignees 테이블)
  - 2025_01_09 → 2025_12_26_183200 (process_type → process_id)
- process_type → process_id 마이그레이션에 멱등성 체크 추가
  - 컬럼 존재 여부 확인 (Schema::hasColumn)
  - FK 존재 여부 확인 (information_schema 쿼리)
