gauges: reconstruct cmArmor -- the per-zone ARMOR DAMAGE schematic [widget recon 3]

Each armor zone on the cockpit schematic is now tinted by that zone's live
damage. Render-verified: the schematic shows an all-green Blackhawk (all zones
damageLevel=0 at spawn), replacing the static green+red it showed before cmArmor
was registered -- i.e. cmArmor now owns those zone colors and shows the real
undamaged state; damaged zones shift toward red.

Reuses the ColorMapper base (from cmHeat) + two pieces reconstructed from the
binary (Ghidra dropped the x87, recovered by disassembly):
- ArmorZoneConnection (@004c33a4/@004c3430): resolves one zone from the owner's
  inherited Entity::damageZones[zone_index]; per-frame feed = zone==NULL ? 100
  : Round(zone->damageLevel * 100) (the 0..1 damage ratio -> 0..100 percentage
  -> the colour index ColorMapper::Execute pushes into the palette slot).
- ColorMapperArmor::Make/ctor (@004c3aa4/@004c3b98): Make resolves the CFG zone
  name (dz_ltorso etc., the 6th param) to an index via Entity::GetDamageZoneIndex
  (== the binary's FUN_0042076c, scanning damageZones[] by name); the ctor wires
  the ArmorZoneConnection.

Decomp fact (corrects the cmHeat note): the ColorMapper base ctor takes NINE
args -- an owner_ID sits between renderer and graphics_port_number. Our 8-arg
ColorMapper::ColorMapper folds owner_ID=0 in (gauges have owner 0), so it is
equivalent; cmArmor's mapping matches cmHeat plus the zone name.

Verified: parses, builds, all dz_* zones resolve (0 "not found"), no /FORCE
unresolved, combat un-regressed (TARGET DESTROYED, 0 crashes). The dynamic
red-on-damage needs the player to take damage (the passive spawn dummy never
hits back). Details: docs/GAUGE_COMPOSITE.md.
