Andrew Stoltz 7a86c40cf1 fix(telephony): ARI receive timeout 45s->3600s — the real false-abort root cause ...

Cancelling ClientWebSocket.ReceiveAsync via CancellationToken ABORTS the
socket (a half-read WS frame can't resume). The per-iteration
iterationCts.CancelAfter(WebSocketReceiveTimeoutSeconds) therefore aborted a
healthy idle ARI WebSocket every 45s (state=Aborted), not the keepalive pong
(proven: loop persisted after pong-timeout 15s->3600s). A large receive
timeout lets ReceiveAsync block harmlessly while the PBX is idle; real drops
still surface immediately as WebSocketException -> reconnect. Proper code fix
(stop using CancelAfter on the receive) tracked separately.
