Given a function $f(x) = m\ln{x} + nx$ whose tangent at point $(1, f(1))$ is parallel to the line $x + y - 2 = 0$, and $f(1) = -2$, where $m, n \in \mathbb{R}$,
(Ⅰ) Find the values of $m$ and $n$, and determine the intervals of monotonicity for the function $f(x)$;
(Ⅱ) Let $g(x)= \frac{1}{t}(-x^{2} + 2x)$, for a positive real number $t$. If there exists $x_0 \in [1, e]$ such that $f(x_0) + x_0 \geq g(x_0)$ holds, find the maximum value of $t$.
