fix(ds-app): category-counts 계약 정정 — 합성된 shape 을 라이브 실측으로 재캡처

라이브 결선 첫 실로그인에서 decode 실패(Key 'total' not found) 진단:
서버 /documents/stats/category-counts 는 Pydantic response model 없는
raw dict 반환({counts:{category:n}, library_pending_suggestions}) — 초기
계약 추출('실 Pydantic 에서 추출')이 이 엔드포인트에선 shape 을 합성
(total/by_domain/review_pending/pipeline_failed = 실재하지 않음).

- CategoryCounts 모델 = 실측 shape + total 파생 접근자(counts 합)
- fixture 2사본(contract/fixtures + DSKit Resources) = CAPTURED_LIVE 재캡처
- DashboardView 스켈레톤 정합(카테고리 분포 + 한국어 라벨, 본격 재설계는 FU-E)
- CONTRACT.md 해당 행 정정 주석

전 엔드포인트 라이브 shape 전수 대조(토큰 생성 후 11종 curl + shape_diff):
stats 외 진짜 drift 0 — documents/tree·search·memos·digest·auth_me·detail·
content 일치. original_filename/duplicate_* 부재 = S1 미배포(optional 이라
무해, 배포 시 해소) / md_frontmatter·memo_task_state = JSONValue 오픈 shape
데이터 차이(무해) / duplicates 422 = S1 라우트 미배포(예상).

검증: swift test 82/82 + shape_diff (shape identical) + xcodebuild PASS.
