feat(piezo): 도넛 위 status chip 을 posture 아이콘+텍스트로 교체

- urgency message Text 자리에 자세 chip (아이콘 + 라벨) 배치
- 색·아이콘·라벨이 currentPosture 에 따라 Crossfade 300ms 로 부드럽게 전환
- top bar 의 작은 inline posture Row 제거 (중복 표시 방지)
- UNKNOWN 상태 가시성 ↑ : tint #616161 + 라벨 'Detecting' (회색 투명+'—' 대비)
- Raw BLE 녹화 버튼은 dev 모드에서만 노출 (legacy 유지)
