In the rectangular coordinate system $xOy$, a polar 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 circle $C$ is $\rho^2 - 2m\rho\cos\theta + 4\rho\sin\theta = 1 - 2m$.
(1) Find the rectangular coordinate equation of $C$ and its radius.
(2) When the radius of $C$ is the smallest, the curve $y = \sqrt{3}|x - 1| - 2$ intersects $C$ at points $A$ and $B$, and point $M(1, -4)$. Find the area of $\triangle MAB$.
