fix: treat post-SaveConfig disconnect as expected, not an error

Browse source 
After all 23 commands write successfully, the DX-Smart beacon reboots
to apply config — dropping the BLE connection. ScanView's disconnect
handler was racing the async writeConfig return and logging this as
"Unexpected disconnect: beacon timed out" even though provisioning
succeeded.

Added writesCompleted flag so the disconnect handler knows writes
finished and logs it as expected behavior instead of an error.
