Experience levels WIRED: the egg field drives the simulation tier (Gitea #2)

BTPlayer's master ctor now seeds the flag block from
btMission->ExperienceLevel() + AdvancedDamageOn() (accessors from the
SURVIVED 1995 BTMSSN.HPP [T0]) instead of the NULL-stubbed scenario
role -- the egg experience knob works for the first time.  Both switch
slot errors fixed vs the binary @4c0bc8; phantom btMission duplicate
member removed (+0x1f8 IS Player::playerMission).

SEVEN gate stubs unified onto the real flags (two found empirically):
HeatModelActive, OwnerAdvancedDamage, LiveFireEnabled,
ControlsAllowLights, powersub @4b0efc, emitter's file-local FUN_004ad7d4
+ FUN_004ac9c8 stubs.  FUN_004ac9c8 family swept (incl. a live raw-offset
databinding trap in MechSubsystem::IsDamaged).  Flag block renamed to its
true semantics (simLive/heatModelOn/...), scoring-era names kept as
comments.  Includes the #5 [aud-tail] diag in emitter.cpp.

ALL 19 shipped eggs say experience=expert -> default behavior UNCHANGED
(per-tier verified: novice/standard = no heat/jams, authentic; veteran/
expert = today's exact behavior).  Real delta: egg advancedDamage=1 now
reaches player+0x264/0x268 (was hardwired 0).  Follow-up flagged: the
glass FE defaults empty experience to veteran (one tier below shipped).

Awaiting human verification.
