style: 저장소 전체 포맷터 일괄 적용 (prettier·biome·ruff)

파일마다 포맷 폭이 달라(≈80 대 100) 한 줄만 고쳐도 포맷터가 무관한 줄을 대량
재포맷했음. 사용자 지시로 전체를 한 번에 맞춤. 코드 동작 변경 없음 — 포맷만.

- 프론트엔드 `.ts/.css/.html` → 저장소 prettier (`.prettierrc`, printWidth 100)
- `B07_DesignDetail/openwebcad/**` → 자체 biome (tab 들여쓰기·single quote·lineWidth 100).
  `biome format` 만 사용 — `biome lint --write` 는 포맷 아닌 코드 수정까지 하므로 제외
- 파이썬 → `ruff format` (엔진 코드는 이미 정합, resources·scratch 스크립트 24개만 변경)

두 포맷터가 서로 되돌리지 않도록 `.prettierignore` 신규 — openwebcad 와 빌드·산출물
폴더를 prettier 대상에서 뺌. `.prettierrc` 에 `endOfLine: "auto"` 추가 — 기본값 `lf` 가
`core.autocrlf=true` 로 받은 CRLF 파일을 매번 전부 다시 써서 `--list-different` 가
실제 포맷 차이를 가리고 있었음.

검증: `tsc --noEmit` 통과(루트·openwebcad 둘 다), pytest 349 passed / 17 skipped /
0 failed, CAD vitest 87건 중 81 passed / 6 failed(laptop-sub 기준선과 동일, 회귀 없음).
포맷터 재실행 시 prettier·biome 모두 변경 0건.
