(Elective 4-4: Coordinate Systems and Parametric Equations)

In the rectangular coordinate system $xOy$, a pole coordinate system is established with the coordinate origin as the pole and the positive semi-axis of the $x$-axis as the polar axis. The polar coordinate equation of the curve $C_{1}$ is $\rho \cos \theta =4$.

(1) Let $M$ be a moving point on the curve $C_{1}$, and let $P$ be a point on the line segment $OM$ such that $|OM|\cdot |OP|=16$. Determine the rectangular coordinate equation of the trajectory $C_{2}$ of point $P$.

(2) Let point $A$ have polar coordinates $(2,\dfrac{\pi }{3})$, and let point $B$ be on the curve $C_{2}$. Determine the maximum area of the triangle $OAB$.
