Let $p$ be the condition that a real number $x$ satisfies $x^2 - 4ax + 3a^2 < 0$ (where $a \neq 0$), and let $q$ be the condition that a real number $x$ satisfies $x^2 + 2x - 8 > 0$. Given that the contrapositive of the proposition "If $p$, then $q$" is true, determine the range of values for the real number $a$.
