Going to e.g. the workboard of an archived project, there is no indication when the project has been archived (the blurred project icon is only displayed if the viewport width is >920px). This can lead to confusion why a workboard is completely empty.
Thus render an archived project as strike-through in the navigation bread crumbs.

Closes T15890

• Go to the {Profile, Workboard, Reports, Members, Subprojects, Reports} pages of an active and an archived project and look at the navigation crumbs bar below Phorge's global top bar.
• Create an active subproject and active milestone of an archived project (and vice versa) and look at the navigation crumbs.
