system
In the Cartesian coordinate system $xOy$, the parametric equation of curve $C_1$ is $\begin{cases}x=-2+2\cos \theta \\ y=2\sin \theta\end{cases}$ (where $\theta$ is the parameter), and in the polar coordinate system with the origin as the pole and the positive $x$-axis as the polar axis, the polar equation of curve $C_2$ is $p\sin \left(\theta+ \dfrac{\pi}{4}\right)=2 \sqrt{2}$.  
(Ⅰ) Directly write out the ordinary equation and polar equation of $C_1$, and directly write out the ordinary equation of $C_2$;  

(Ⅱ) Point $A$ is on $C_1$, and point $B$ is on $C_2$, find the minimum value of $|AB|$.
