Fix operator precedence in character creation validation

[kwsantiago]

Summary

The parentheses in validateCharacterCreation are misplaced, causing iHeight, iNameCheck, and iSkinColor to never be validated.

The current code:

if (!(... && style->iHairColor <= 18) &&
      style->iHeight    >= 0 && ...
      style->iSkinColor >= 1 && style->iSkinColor <= 12)

The ) closes after iHairColor, so the expression becomes !(A) && B && C && D instead of the intended !(A && B && C && D). This means a client can send arbitrary values for height, name check, and skin color.

What changed

Moved the closing ) to the end of the full condition, matching the intended logic.
