feat(dashboard): Network summary has each server's port and machine

The dashboard keeps master's server list endpoints and joins them into the
Network summary: its listening port and its machine as a token, since the
summary goes to every open page. The connection list maps the tokens to
addresses for viewers with network_ips. The dashboard reports its web port.
