Fix editing a Help Center Page workflow

Clicking the "Dashboards" button on a helpdesk article should link back to the articles page in the Help Center instead of continuously redirecting the user to the /dashboard/posts page.

This is currently one of the most frustrating workflows because rather than simply viewing a page and editing it directly (View Page → Edit Page), the process becomes unnecessarily complicated (View Page → Click Help Center → Search for Page → Edit Page).
