feat: 작업일지/중간검사 설정을 ProcessStep → Process 레벨로 이동

- Process 모델에 document_template_id, needs_work_log, work_log_template_id 추가
- ProcessStep에서 해당 필드 제거
- WorkOrderService의 검사 관련 3개 메서드(getInspectionTemplate, resolveInspectionDocument, createInspectionDocument) 공정 레벨 참조로 변경
- ProcessService eager loading에 documentTemplate, workLogTemplateRelation 추가
- FormRequest 검증 규칙 이동 (ProcessStep → Process)
