fix: cross-channel outlier 제거 + placement 강화 + UI 수정

- Cross-channel urine length outlier: median의 1.35x 초과 또는 0.5x 미만 → 제거
  (CH3 바닥반사 urine=50 vs 정상 ~35 → 480ml↔223ml 편차 해결)
- Placement CV: V0=0.07, V1/V2=0.10 (기기별 분기)
- Placement 기준 강화: LR dev 0.20, gradient 0.3, lenVariation 0.35
- "방향OK→무조건GREEN" 제거, CV 미달시 "Fine-tune position"
- GREEN CV가이드/Hold steady 제거, ch별 len 분석 방향 안내
- 가이드 텍스트 상자 항상 표시
- 센서 이미지 topview 교체 (240×150dp)
- 앱 버전 VBTAND0101
- Plot/Log allWalls 통일 (선택 Method 기준)
