- summary.current_month_total → current_month_amount 변경
- summary.previous_month_total → previous_month_amount 변경
- monthly_trend[].month → label 변경 ("2025-07" → "7월")
- by_type[].label → type_label 변경
- by_type[].color 필드 추가 (차트 색상)
- items[].date → purchase_date 변경

프론트엔드 transformer와 API 응답 구조 일치
