Added centralized color config ZONE_COLORS and helper GetZoneColor.
Replaced all hard-coded color draws with ZONE_COLORS/GetZoneColor:
OnEnterGuarded, OnEnterEmpty, OnEnterAttacked, OnEnterCaptured.
ZoneColorVerification (periodic).
RefreshAllZoneColors (manual).
Hardened scanners with nil/pcall guards:
GetZoneForceStrengths now checks ZoneCapture and safely gets the zone.
CreateTacticalInfoMarker now pcall-guards zone access and avoids nils.
Made tactical text coalition-specific:
BLUE sees RED TGTS (<=10 units).
RED sees BLUE TGTS (<=10 units).
Both markers include the same force summary, but TGTS is tailored per viewer coalition.
Add ZONE_COLORS/GetZoneColor and replace color usages.
Harden GetZoneForceStrengths and CreateTacticalInfoMarker with nil/pcall guards.
Make tactical text coalition-specific so each side only sees enemy TGTS.
