fix(demo): 정렬모드 Skip top bar 우측 노출 + 개인화 페이지 한글화

1. PlacementGuide top bar 에 Skip TextButton 추가
   - 기존: scrollable Column 맨 아래 → 스크롤 안에 묻혀 안 보이던 문제
   - 변경: top bar 우측 (Back / Ready / Skip / [dev] Settings 순) 항상 가시
   - 동작: clinical alignment → endMeasurement + CLINICAL_HOME / 일반 → placementComplete

2. PiezoPersonalizationView (개인화 페이지) 한글화
   - 'Maximum Bladder Capacity' → '최대 방광 용량'
   - 'Voiding Reminder' → '배뇨 알림 기준'
   - 'Auto Scan Interval' → '자동 측정 주기' (기존 key 재사용)
   - 'Continue' → '계속' (기존 calibration_continue 재사용)
   - 'Back' (contentDescription) → '뒤로'
