Given that \( F_{1} \) and \( F_{2} \) are the left and right foci of the hyperbola \( C: \frac{x^{2}}{4}-\frac{y^{2}}{12}=1 \), and point \( P \) lies on the hyperbola \( C \). Let \( G \) and \( I \) be the centroid and incenter of \( \triangle F_{1} P F_{2} \) respectively. If \( G I \) is parallel to the \( x \)-axis, find the circumradius \( R \) of \( \triangle F_{1} P F_{2} \).
