If the sequence $\{a_n\}$ has a partial sum of $S_n$ for the first $n$ terms, and the point $(n, S_n)$ is on the graph of the function $y = \frac{3}{2}x^2 - \frac{1}{2}x,$
(Ⅰ) Find the general term formula for the sequence $\{a_n\}$;
(Ⅱ) Let $b_n = \frac{3}{a_n a_{n+1}}$, and let $T_n$ be the partial sum of the first $n$ terms of the sequence $\{b_n\}$, find $T_n.$
