music_quiz: btn_prep/btn 의 정렬용 다중 공백 제거 — Brigadier 파싱 에러 회피

btn_prep.mcfunction line 10 에서 'Incorrect argument at position 45'
파싱 에러 발생. 이유는 보기 좋게 맞추려고 컬럼 정렬용으로 연속 공백을
넣었는데 MC 26.1.2 의 명령 파서가 컬럼 정렬을 토큰 구분으로 처리하지
못해 다음 인자를 못 찾음.

btn.mcfunction 의 가운데 타일 summon 라인 (~0.5   ~0.375 같이 두 칸
띄운 곳들) 도 동일 패턴 → 한 칸 공백으로 정규화.
