feat(790-2): 단가산출 숫자 넓힘 서버 — 상수 · 표값 덮개 · 글줄 · 까닭 · M01 원래로 · M01판

- 새 M02_Sangeun_Const.py — 식 n 번째 숫자 · 표 찾기 덮개(엔진 파서 차례 · 식 구조 그대로라 옵션 따라감) · 글줄 · 까닭 꼴 검사 · 저장 때 M01판(자리마다 지문) · 셈 답 덧칸 원래 {노 · 재 · 경 · 계} · 시트 {자리 · 글줄 · 짝잃음}
- Doc.patched 첫머리 · clean 끝 · Calc.clean_doc · calc_doc 한 줄씩 끼움(줄 수 그대로) — 화면 · 저장 원값 · B09 · 펼침 겹침 한 벌
- Library_Flat — 상수 · 표값 덮개 SK 는 안 펼침(참조 그대로 · 값 그대로) · [초기화]가 새 덮개 · 까닭도 걷음
- 새 logic/M02_Sangeun_Const_Model.ts — 캐시 고치기(setConst · setTable · 글줄 · setReason · restoreM01 · dropAddKeys · coverKinds) · 파이썬 짝 거울 시험
- 새 test_790_2_sangeun_const.py — 견본 금액 = _분석_650-H2(61,088 · 51,802 · 38,696 · 35,764) · 옛 SK 꼴 · 금액 그대로
