feat(schedule): 공정표 제품유형 + 표준공정 자동생성 백엔드

- product_types 참조 테이블 + projects.product_type_id FK (tkuser 마이그레이션)
- schedule_entries에 work_type_id, risk_assessment_id, source 컬럼 추가
- schedule_phases에 product_type_id 추가 (phase 오염 방지)
- generateFromTemplate: tksafety 템플릿 기반 공정 자동 생성 (트랜잭션)
- phase 매칭 3단계 우선순위 (전용→범용→신규)
- 간트 데이터 NULL 날짜 guard 추가
- system1 startup 마이그레이션 러너 추가
