문서 고도화 다음 단계를 반영해 XLSX·HTML·PPT 품질 게이트를 강화했습니다

핵심 수정사항:
- ExcelSkill summary_sheet에 trend_series를 추가해 Trend Dashboard 블록을 렌더링하고, workbook quality review가 dashboard형 summary 구성을 더 정확히 평가하도록 확장했습니다.
- HtmlSkill은 print=true인데 print_header/print_footer가 없는 경우 기본 print frame을 자동 생성하도록 보강했고, ArtifactQualityReviewService는 print-ready 문서의 frame/decision/evidence/cover 부족을 추가 경고로 반환합니다.
- DeckPlanningService는 comparison, roadmap, executive_summary, kpi_dashboard 슬라이드의 최소 구조를 자동 보정하고, DeckQualityReviewService는 slide-level quality gate를 추가해 긴 headline, 과밀 슬라이드, 옵션 부족, 표/차트 데이터 누락을 Slide N 경고로 요약합니다.
- DeckQualityReviewServiceTests, ExcelSkillDashboardSummaryTests, HtmlSkillPrintFrameTests를 확장해 회귀 검증을 강화했습니다.

검증 결과:
