Given that $\overrightarrow{a}=( \sqrt{3}\sin x,\cos x+\sin x)$, $\overrightarrow{b}=(2\cos x,\sin x-\cos x)$, and $f(x)=a\cdot \overrightarrow{b}$.
(1) Find the monotonically increasing interval of the function $f(x)$;
(2) When $x\in[ \frac{5\pi}{24}, \frac{5\pi}{12}]$, the inequality $mt^{2}+mt+3\geqslant f(x)$ always holds for any $t\in\mathbb{R}$. Find the range of values for the real number $m$.
