Project: unify project version listing URLs/links

On the new dashboard, the project detail view is the project versions list. However, on the backend these are still separate as the views differ in production. The main difference is that the function view public.project_versions doesn't implement the same logic and filtered that exists on the detail page already.

The eventual goal should be:

• ProjectDetailView becomes VersionListView
• public.project_versions function view goes away
• The ProjectDetailView URL basically goes away, and /project/slug/versions is the URL for the project dashboard. This is effectively the UX already, as the selected tab is the versions tab on the detail view page:

For now, all of the links could use the reverse lookup URL for project_version_list:

• Project base template
• Build detail and listing page
• Version popupcard

Does this plan make sense? Does is seem okay to consolidate these views under /projects/slug/versions/?

Start by reviewing the Project base template, Build detail and listing page, Version popupcard, and the public.project_versions function view. Compare the existing detail-page logic with the versions listing and trace links that should use the project_version_list reverse lookup URL. Done means the consolidation plan is resolved and the affected links and views have an agreed target under /projects/slug/versions/.
