feat(dragonwilds): MATCH_PUBLIC so the join code works behind a relay

The server advertises the address its outgoing traffic comes from, so it
binds its public ports (-Port / -BeaconPort from {PUBLIC_PORT_n}) and, behind
Public Bypass, sends its traffic out through the relay. Adds portMode to the
schema and to import's field order.
