gauge-complete P4a: heat-leaf data fixes (radar heat-degradation authentic)

Browse Source 
The gauge-complete-decode workflow found the "deep heat-leaf byte-exact re-base" is
STALE -- the leaf layout already shipped byte-exact (alarm-unification/P7), and the
real work is a small misidentified-field data fix (highest value, lowest risk):

- Sensor radarPercent read the INHERITED heatEnergy (~1.3e7) -> hugely negative ->
  needed a bring-up guard forcing it to 1.0.  The binary (@004b1c4c:1829) reads
  *(this[0x38]+0x158) = the subsystem's OWN DamageZone::damageLevel [0,1] (0 intact ..
  1 destroyed).  Fixed: radarPercent = RadarBaseline - GetSubsystemDamageLevel(); guard
  DELETED (damageLevel is engine-clamped).  So the radar authentically degrades with
  sensor structural damage (RadarBaseline-damage, x0.5 on DegradationHeat, 0 on Failure).
- New databinding-SAFE accessor MechSubsystem::GetSubsystemDamageLevel()/Set... reads the
  ENGINE DamageZone::damageLevel NAMED member (NOT the ReconDamageZone proxy, whose
  offset-0 structureLevel aliases the vtable ptr as a float = garbage).
- HeatSink::HandleMessage msg==1: same misidentification -> SetSubsystemDamageLevel(0.5)
  (was linkedSinks->heatEnergy=0.5, wrong object+field).
- MyomerCluster seek lamp: subsys+0x800 (OOB for 0x358 Myomers) -> currentSeekVoltageIndex
  @0x320 (the Emitter+0x3f0 analog; INFERRED -- ctor not in the assert-anchored export).
- numericSpeed (~225 vs 61.5): verified NOT A BUG (NumericDisplaySpeed applies x3.6; the
  feed is correct u/s) -- closed, no code.

No layout change (already byte-exact); pure data-read retargets.  Verified DBASE+dev
gauges: no crash, combat un-regressed (TARGET DESTROYED).  (radarPercent degrade is only
OBSERVABLE once per-subsystem damage routes to each engine DamageZone -- a separate task;
today the sensor is undamaged so radarPercent = full 1.0, which is correct.)
