feat: 펌웨어 버전 앱 내 표시 (Settings + ClinicalHome)

연결 시 자동으로 받던 mid?/rid: device_info를 UI에 노출. 이전에는 BLE 디버그 로그에만
기록되어 사용자가 접근 불가했음.

BleManager:
- firmwareVersion / hardwareVersion / serialNumber 3개 MutableState 추가
- rid: 응답 파싱 — "VBTHW0100   VBT26040001 VBTFW0111" 형식을
  공백 split + prefix 매칭(VBTHW/VBTFW/VBT)으로 안전 추출
- disconnect 시 3 필드 모두 clear

PiezoMonitoringView Settings overlay:
- 기존 "Version" 행을 "App" + "Firmware" 두 행으로 분리
- FW 없으면 "—" 표시 (연결 대기 중)
- dev 모드 한정 "Serial" 행 추가 (회사 자산 추적용)

ClinicalHomeView BLE 연결 카드:
- deviceName 아래 "FW: VBTFW0116" 한 줄 추가
- 검사자가 별도 클릭 없이 펌웨어 버전 즉시 확인 가능
