netcode-revival: force the frontend 'enter online flow' gate (sub_82703960)

create-party (sub_82A1B8E0) is only reached through the frontend online
flow, gated by sub_82703960 which requires: online latch 0x830670C8 == 0,
frontend-mode byte obj@*(0x8306707C)+194 != 0, XamUserGetSigninInfo.unk08==1
(already), and a mode check. Force the two state inputs and log the gate
inputs in the periodic dump so we can see exactly which check blocks.
