Given $f(x) = e^{\frac{x}{2}} - \frac{x}{4}$, where $e$ is the base of the natural logarithm.
(1) Let $g(x) = (x+1)f'(x)$ (where $f'(x)$ is the derivative of $f(x)$), determine the monotonicity of $g(x)$ on $(-1, +\infty)$;
(2) If $F(x) = \ln(x+1) - af(x) + 4$ has no zeros, find the range of values for the positive number $a$.
