fix(client): remove AP net monitor WS terminate (scheme A)

AP mode no longer periodically terminates WebSocket when hasInternet and
hasWiredInternetProbe both fail; avoids false positives with hotspot + wired
uplink. Reconnect and offline detection rely on Pong, peer close, and TCP.

_connect() still defers new WS when AP and no uplink; close handler UI unchanged.
