Steam transport: identity-resolved accepts + load-proof timeout

Browse Source 
Round four reached one step from the race: eggs delivered, both
members ACKed with complete meshes, one member entered LoadingMission.
Two failures remained, both now fixed.

One: Steam reports incoming callers under locally-allocated ALIAS
FakeIPs, not their global ones - the owner accepted both mesh legs
but its identity check compared the alias against the egg address and
never counted the connections (no Connected to GameMachineHost on the
owner). The peer table now carries each member SteamID (lobby go
roster gained a field) and Accept resolves the caller identity back
to the global FakeIP the egg promised.

Two: mission load stalls the game thread for 10-30s with nothing
pumping, and Steam default 10s connected-timeout sheared every
connection mid-load (end reason 4001, rx ages 11.5-20.5s - right at
load duration). Connected timeout is now 90s; TCP never timed out an
idle arcade link and races pump every frame once running.

Self-test still green (ping, survives listener close).
