feat(memos): UX 개선 — 편집 수정, 제목 제거, 체크박스, 아카이브

Phase A: 편집 버그 수정 (content만 PATCH, Ctrl+Enter/Esc),
제목 UI 제거 (자동생성 80자, 내부용), 카드 경량화.

Phase B: GFM task list 지원, taskIndex 기반 인터랙티브 토글,
DOMPurify checkbox 최소 허용, optimistic update + 롤백.

Phase C: archived 컬럼 (메모 UX 전용, 문서 미노출),
멱등 세팅 API (토글 아님), 활성/아카이브 뷰 분리 쿼리,
핀은 활성 메모용 (archived 시 무시).
