feat(M02): 도면 양식 편집 부품 mountDrawingTemplate — 도각 편집 모드 · 자리표 키 · 작도 영역 · 자동백업 칸 M02 용 (PLAN 10-3)

- M02_MasterTemplete_Drawing.ts · .css — (칸, 문서, {onSave, readOnly, name}) → {getDoc(Promise), destroy}
- cad_host load 곁값 recoveryScope · readOnly
- CAD 앱 브리지 — 싣기 메시지의 recoveryScope(없으면 meta.drawingId) · readOnly(확정본과 같은 막힘)
