netcode-revival: fix the live-flag address + force the live-user cache flags

The live-flag address was wrong: sub_8263E788's lis r11,-32003 gives
r11 = -2097348608 = 0x82FD0000 (recompiler value + 2^32), so the flag is at
0x82FC8851, not 0x83028851 (an arithmetic slip mis-multiplied 0x82FD0000).
We were forcing/reading an unrelated mapped byte, so the gate never saw the
forced value. Also force the game's cached 'live user exists' flags the
frontend online-access controllers check: 0x8308396C (14700) and 0x83084690
(18064).
