feat(ui): Phase E — PreviewPanel 분할 + detail inline + viewer Tabs

E.1 PreviewPanel 7개 editors/* 분할:
- frontend/src/lib/components/editors/ 신설 (7개 컴포넌트):
  * NoteEditor — 사용자 메모 편집
  * EditUrlEditor — 외부 편집 URL (Synology Drive 등)
  * TagsEditor — 태그 추가/삭제
  * AIClassificationEditor — AI 분류 read-only 표시
    (breadcrumb + document_type + confidence tone Badge + importance)
  * FileInfoView — 파일 메타 dl
  * ProcessingStatusView — 파이프라인 단계 status dl
  * DocumentDangerZone — 삭제 (ConfirmDialog 프리미티브 + id 고유화)
- PreviewPanel.svelte 344줄 → 60줄 얇은 wrapper로 축소
  (header + 7개 editors 조합만)
- DocumentMetaRail (D.1)과 detail 페이지(E.2)가 동일 editors 재사용

E.2 detail 페이지 inline 편집:
- documents/[id]/+page.svelte: 기존 read-only 메타 패널 전면 교체
- 오른쪽 aside = 7개 editors 스택 (Card 프리미티브로 감쌈)
- 왼쪽 affordance row: Synology 편집 / 다운로드 / 링크 복사
- 삭제는 DocumentDangerZone이 담당 (ondelete → goto /documents)
- loading/error 상태도 EmptyState 프리미티브로 교체
- marked/DOMPurify renderer 유지, viewer 분기 그대로

E.3 관련 문서 stub:
- detail 페이지 오른쪽 aside에 "관련 문서" Card
- EmptyState "추후 지원" + TODO(backend) GET /documents/{id}/related

E.4 DocumentViewer Tabs 프리미티브:
- Markdown 편집 모드의 편집/미리보기 토글 → Tabs 프리미티브
- 키보드 nav (←→/Home/End), ARIA tablist/tab/tabpanel 자동 적용

검증:
- npm run build 통과 (editors/* 7개 모두 clean, $state 초기값
  warning은 빈 문자열로 초기화하고 $effect로 doc 동기화해 해결)
- npm run lint:tokens 204 → 168 (detail 페이지 + PreviewPanel 전면
  token 기반 재작성으로 -36)
