feat: 자동측정 IMU 1초 + 전체측정(mbb) 10초 루프

자동측정 변경 (기존: 30초 maa → 신규: 1초 msp + 10초 mbb):
- 1~9초: msp(IMU query) → rsp(accel+gyro) 1초 간격
- 10초째: mbb(전체측정) → rbb(헤더) + reb×6 + raa
- 기존 maa → mbb(sendFullMeasurement)로 전환
- mbb 응답은 rbb: 헤더 후 reb:/raa: 동일 파이프라인

BLE 명령어 추가:
- sendImuQuery(): msp 전송
- sendFullMeasurement(): mbb 전송 (piezoCollector 연동)
- sendLedMode(state): mls 전송

응답 파싱 추가:
- rxs: → "cmd_not_supported" (mid? 미지원 기기 대응)
- rbb: → full measurement header
- rsp: → IMU data
