기존 finalStop 조건이 `phase == LR_BALANCE` 만 인정했는데, 실제로는
LR_BALANCE 에서 imbal 통과 즉시 `phase = FINAL_CONFIRM` 으로 바뀌어
반환되므로 이 조건에 걸리지 않았음. FINAL_CONFIRM 5프레임 도달 후
STOP + align_complete 반환 시점에도 phase 는 FINAL_CONFIRM 이라
finalStop=false → isLocked 유지 안 됨 → 버튼 disabled.

수정: state=="commit" && phase==FINAL_CONFIRM && action==STOP 을
진짜 정렬 완료로 인정. Accum 중은 이미 앞 branch 로 빠지므로 안전.
