fix(B07): 도면 불러오기 — bulge 호 · OCS 거울 블록 · TEXT 정렬점 · 겹 블록 풂(84-2)

Browse Source 
- LWPOLYLINE/POLYLINE 은 ezdxf path.make_path().flattening(0.2) 로 — bulge 호 마디 펴짐 · 압출 −Z 는 WCS 로
- TEXT 는 get_placement 정렬점 · OCS → WCS · 가로 정렬(왼 · 가운데 · 오른) · MTEXT 붙임점 가로 정렬
- INSERT 속 INSERT 까지 풂(16 겹 한도)
- 견본 DXF 시험(호 · bulge · 거울 블록 · 겹 블록 · TEXT 정렬) — 옛 코드에선 넷 실패
