vehicleSubSystems follow-up: reconstruct SegmentArc270 recharge dial

Browse Source 
Reconstruct SegmentArc270 (@004c6244): engine SegmentArc base + a Scalar connection
driving currentValue + the |n|/(|n|-1)*0.75 segment-span factor.  Wire it into
WeaponCluster as the recharge dial (was a deferred NULL), reading the weapon's real
PercentDone attribute.  Render-verified (BT_DEV_GAUGES_DOCK): the green segmented
recharge circles draw in the weapon panels; 7 panels build, 0 crashes.
