Setup에 Auto Scan Interval 카드 추가 + BLE 끊김 banner 제거 (silent reconnect)

PiezoPersonalizationView:
  - AutoScanIntervalCard 신규 — 600~5000ms 슬라이더 + ±200ms 스테퍼
    기존 MaxVolume / CatheterThreshold 카드와 동일한 톤
  - 3카드가 화면을 넘칠 수 있어 verticalScroll로 전환, spacing 64→24dp

PiezoMonitoringView / VivamyoMonitoringView:
  - 사내 테스트 피드백: BLE 끊김 banner가 자주 튀어 거슬림. BleManager 측
    scheduleAutoReconnect()가 이미 백그라운드로 재연결을 시도하므로 UI
    알림은 불필요.
  - onUnexpectedDisconnect/onReconnectionFailed/onConnectionStateChanged
    콜백에서 banner state 토글 제거. 측정 일시정지 및 batteryPolling 재시작은
    그대로 유지.
  - 미사용 state (showDisconnectionBanner, reconnectionState) + 관련 import
    정리. BleDisconnectionBanner.kt 파일 자체는 후속 사용 가능성 위해 남김.
