UI: 힌트 위치 이동 + 버튼 텍스트 + Alignment 비활성 + Bladder Capacity

#1 Placement 힌트 메시지: 몸 아래 → Step 아래/몸 위로 이동
#2 버튼 텍스트: Catheterize→Catheterization, Auto→Automatic, 글자 크기 UP
#3 Alignment Complete: GREEN(Optimal)일 때만 활성 (Skip과 차별화)
#4 Max Volume → Bladder Capacity (설정+Personalization 모두)
- Bladdy 도넛 내 위치 3% 위로 보정
