* fix: prevent QUIC reload panic by lazily initializing the listener
ServePacket on reload receives the reused PacketConn before the new
ServerQUIC has recreated its quic.Listener, so quicListener is nil and
the process panics. Lazily initialise quicListener from the provided
PacketConn when it’s nil and then proceed with ServeQUIC.
