Fix Sunstrider Isle areaId override for GetAreaIdByUiMapId

When UpdateNearestTargets uses ZoneDB:GetAreaIdByUiMapId(946) to verify
player zone, it returns 668 (Northshire) instead of 3430 (Sunstrider).
UiMapIdOverrides[946] was set to 668 for Northshire, so 946 always
resolves to Northshire's areaId even on Sunstrider Isle.

Added direct cache entries for both 1241→3430 and 946→3430 in the
uiMapIdToAreaIdCache (the fast-path lookup table) so GetAreaIdByUiMapId
returns the correct Sunstrider Isle areaId regardless of which map ID
the game returns.
