tools: add icons to move and restore on-canvas text editor position

This commit adds a button inside the on-canvas text editor
that restores the editor to its original position after it has
been moved. The button is only visible when the editor has been
moved, and disappears when it returns to its default position.
It also adds an icon to indicate that the editor can be moved.
