fix(frontend): route DATA through sendCommand for readValue() fallback 

sendCommandWithRetry now delegates to sendCommand() instead of
using raw writeValueWithResponse + await ackPromise. This ensures
DATA chunks also benefit from the readValue() state poll fallback
when Android BLE notify is unreliable after idle.
