In the Cartesian coordinate system $xOy$, a line segment of length $\sqrt{2}+1$ has its endpoints $C$ and $D$ sliding on the $x$-axis and $y$-axis, respectively. It is given that $\overrightarrow{CP} = \sqrt{2} \overrightarrow{PD}$. Let the trajectory of point $P$ be curve $E$.

(I) Find the equation of curve $E$;

(II) A line $l$ passing through point $(0,1)$ intersects curve $E$ at points $A$ and $B$, and $\overrightarrow{OM} = \overrightarrow{OA} + \overrightarrow{OB}$. When point $M$ is on curve $E$, find the area of quadrilateral $OAMB$.
