iandunn 107b52191b Privacy: Reposition admin pointer to avoid covering collapsed menu.
Previously the pointer overlapped the menu in order to draw attention to the fact that it applies to both the `Tools` and `Settings` menus. That caused a conflict if the menu was collapsed, though, because the icons were covered by the pointer and therefore inaccessible.

Additionally, minor tweaks were made to the text order and formatting. The order of the two sections was swapped in the title and paragraph, in order to match the order of the corresponding menu items. The spacing around headings and paragraphs was tweaked to remove extraneous whitespace.

Props littler.chicken, desrosj, ianbelanger, melchoyce.
Fixes #43961.
