gauge-complete P4b: AggregateHeatSink 0xBBE -> HeatSink/AmbientTemperature bound (last config NULL cleared)

The 0xBBE heat-sink BANK was built as a plain HeatSink, so the numeric-R
cockpit gauge binding HeatSink/AmbientTemperature (L4GAUGE.CFG:4552) had
no publisher -> the LAST unresolved config attribute.

Reconstruct AggregateHeatSink : HeatSink (ctor @4ae8d0, own GUID 0x50e590),
byte-exact + static_assert-locked (heatSinkCount@0x1D0, ambientTemperature
@0x1D4=300, helper@0x1D8 0xC link node, sizeof 0x1E4 == factory alloc @9993).
Publish HeatSinkCount + AmbientTemperature via a dense-prefix attribute table
chained to HeatSink::NextAttributeID (shared HeatSink table unchanged, so
CoolantMass/CoolantCapacity keep resolving). Move CreateHeatSinkBankSubsystem
into heatfamily_reslice.cpp (needs the class def) and build the real class at
factory case 0xBBE; mech.cpp unchanged.

DELIBERATE DEVIATION (documented in the class): keep the base HeatSinkSimulation
the HeatSink ctor installs; do NOT reimplement the authentic Performance @4ae73c
-- it derefs a raw self+0xE0 -> [+0x158] that does not map in our compiled layout
(AV/NaN, and runs for EVERY mech), and ambientTemperature is a frozen constant so
the gauge reads 300 either way. Authentic relaxation model deferred.

Verified: [attr] HeatSink/AmbientTemperature OK; all 50 config attribute
bindings resolve (0 NULL); no every-mech crash; combat TARGET DESTROYED,
FIRED #41+, un-regressed.
