Add screenshots of company and space work maps

[markoa]

• The screenshot of a company work map should appear in the Quick Tour and the corresponding help page
• Quick tour should also refer to it as work map not "goals & projects" any more
• The screenshot of a space work map should appear on the corresponding help page

depends on operately/operately#2709

resolved with #186 and #187. we currently have one page on work maps that covers all flavors btw, hence one screenshot.
