system
In the plane rectangular coordinate system $xOy$, the parametric equations of the line $l_{1}$ are $\left\{\begin{array}{l}{x=t}\\{y=kt}\end{array}\right.$ (where $t$ is the parameter), and the parametric equations of the line $l_{2}$ are $\left\{\begin{array}{l}{x=-km+2}\\{y=m}\end{array}\right.$ (where $m$ is the parameter). Let $P$ be the intersection point of the lines $l_{1}$ and $l_{2}$. As $k$ varies, the locus of point $P$ is curve $C_{1}$. <br/>$(Ⅰ)$ Find the equation of the locus of curve $C_{1}$; <br/>$(Ⅱ)$ Using the origin as the pole and the positive $x$-axis as the polar axis, the polar coordinate equation of line $C_{2}$ is $\rho \sin (\theta +\frac{π}{4})=3\sqrt{2}$. Point $Q$ is a moving point on curve $C_{1}$. Find the maximum distance from point $Q$ to line $C_{2}$.
