Fix tab switching in CatheterizeSheet + camera launch timing

CatheterizeSheet:
- Replace OutlinedButton with filled Button for tab selection
- Selected tab: filled color, unselected: 10% opacity background
- Tabs now reliably switch between 수기/음성/카메라
- Camera tab directly calls onCameraRequested + onDismiss

PiezoMonitoringView:
- Fix camera launch: use pendingCamera + LaunchedEffect
  to ensure ModalBottomSheet fully closes before camera opens
- Prevents state race condition between sheet dismiss and camera show
