feat(497-0 [초기화] 서버): B07 · B08 · B09 reset 창구 셋 — 그 페이지 사용자 값 · 설정 지움 · 올린 파일 남김 · 단계 = 저장

- B07 POST /design-drawings/reset — 저장본 확정 풂(번호 · json 남김) · B07 이 올린 측점 확정 → 잠정 · 축척 · 횡단 배치 · 평면도 종류 · 표식 파일 지움 · 새 _Router_Reset.py(main.py 물림)
- B08 POST /quantity/reset — quantity 설정 구획 기본 · hydro_inputs 지움 · milestone 기본(사용자 그림 붙은 거래처 경로 줄만 남김 · to = 시점) · 1본 길이 · 그림 남김
- B09 POST /estimation/reset — 사용자 값 · 단가 책 · estimation 설정 구획 지움 · 안 쓰는 서고 사본 정리 · 견적서 남김 · 답 = GET 꼴
- 공용 reset_section(구획 하나 기본으로) · 새 시험 test_298_2_page_reset
