stswangzhiping 12aedaaf85 feat(net): late uplink poll + faster provision monitor (15s)
- client: while !_connectionStarted, poll every 3s for hasInternet or
  hasWiredInternetProbe (e.g. Ethernet after AP); start _proceedWithConnection
  once; clear poll on network-ready/stop. Avoids provision-level emit spam.
- provisioning: MONITOR_INTERVAL_MS 30s -> 15s for quicker WiFi/AP UI.
