Let the points $P$, $Q$, and $R$ in the complex plane be represented by the complex numbers $z$, $(2+i)z$, and $3\overline{z}$, respectively, where $|z| = 1$. When $P$, $Q$, and $R$ are not collinear, let $S$ be the fourth vertex of the parallelogram $PQRS$. Determine the maximum distance between $S$ and the origin of the complex plane.
