Given a function $f(x) = \log_a(x+1)$ with $a > 1$, suppose that for the function $y = g(x)$, any point $P$ on its graph has a symmetric point $Q$ with respect to the origin. The trajectory of $Q$ exactly matches the graph of function $f(x)$.
(1) Write down the explicit expression for the function $g(x)$;
(2) When $x \in [0, 1)$, it always holds that $f(x) + g(x) \ge m$, determine the range of $m$.
