⭐ Move list 2 warning to footer

[NickTikhomirov]

We need this package:

\usepackage{fancyhdr}

We're going to modify "default fancy" style, so if we need something else to be done with styles, we will be forced to define a new style.

Clear style:

\fancyhead{} 
\fancyfoot{} 
\renewcommand{\footrulewidth}{0 mm}
\renewcommand{\headrulewidth}{0 mm}

And then (immidiately) build a new world as we want it to be:

\fancyfoot[L]{%
    \vspace{-5ex}
    \fontsize{10}{10}\selectfont
    \noindent Является обязательным листом отчёта по практике. Лист 2\\
    \noindent Документ не должен содержать информацию, отнесённую в установленном порядке к государственной тайне РФ.
}

Justify environment is excessive here (also it breaks defined font and does funny stuff to spacings).

The final step: add \thispagestyle{fancy} to page 2 istead of \thispagestyle{empty}, page 1 needs no modification.
Also the previous (non-footer) version of the warning is expected to be removed
