Improve report page structure (#12615)

* Move resolved button to the heading

This is one of the commits on improving overall reports page structure.
It changes where resolved button is located, moving it to the heading,
right next to the "Report #n" header, so-called "hot-place" to look at.

To accomplish this we have to declare one more content variable, change
admin dashboard template to respect it and CSS files for minor styling,
so buttons are inlined and centrally aligned according to the heading.

* Move actions buttons below the report table

I believe that actions to react on report should not be located at the
top of the page, instead they should be either after the table or
reporter's comment. This is just a logical sign that you should not
react to the report without reading all the details first.
