#118: the eject option comes alive -- per-frame arm chain closed (FUN_004a9b5c+0x10)

Browse Source 
The evaluator's "unexported caller" found by E8-scan: the Mech MASTER
PERFORMANCE (FUN_004a9b5c, in the 004a977x..004ab188 export hole) calls
EvaluateEjectPermission as its FIRST act every frame. Without that call the
port's ejectPermitted stayed at ctor-0 forever -- the panic-armed mode never
raised, so the PANIC lamp never lit and testers "never saw the option for
eject come alive". Restored at the top of Mech::PerformAndWatch (masters
only, like the binary).

Mislabel swept: mech+0x414 is ejectPermitted, NOT "missionReviewMode" -- the
mapper's @004d196c edge-watch arms PANIC mode 0x200000 from it (the real
review mode is the GLOBAL DAT_004fd550; btl4pb now reads that global, the
GetMissionReviewMode stub is retired, mapper member renamed
previousEjectPermitted).

Verified live: kill 4 generators -> "[eject] panic-arm mode ON" -> the
miniconsole Panic button lights dark->bright (pixel captures; the pad panel
shades it from the same PadRIO lamp state the pod's physical button uses) ->
BT_EJECT_AT press -> PUNCH-OUT -> respawn heals -> mode disarms -> healthy
presses REFUSED. BT_EJECT_LOG=1 logs the arm edges.

Note: no shipped gauge rides mode 0x200000 -- the 1995 eject indication is
the button lamp; the weapon-eng MFD "UNJAM/EJECT" is the ammo-jam indicator.
