Implement websocket keepalive pings for websockets-sansio Adds server-side keepalive to the sansio WebSocket implementation using two asyncio.TimerHandle primitives instead of a long-running task. Matches the passive-timer style already used by the HTTP keep-alive in httptools_impl.py, and addresses #2883 for the sansio path. Key points: - Single ping in flight at a time, driven by the chain schedule_ping -> send_keepalive_ping -> handle_pong -> schedule_ping. - Random 4-byte payload per ping, matching the websockets reference. - Latency compensation keeps the effective cadence at ws_ping_interval. - Failure path uses ServerProtocol.fail(1011, "keepalive ping timeout"). - ws_ping_interval <= 0 is treated as disabled (preserves the contract test_client_connection_lost relies on).
