    unetmsg: close all channels on network removal
    
    network_close() only closed the listening socket without shutting down
    established RX/TX connections. This left remote state in
    core.remote_publish/core.remote_subscribe for hosts on the removed
    network, causing stale entries in channel listings and failed routing
    attempts.
    
    Close all RX and TX channels before removing the network, which also
    triggers remote state cleanup via network_rx_socket_close().
