Kill "dashboard"; give entries a home

(stealing your branch)

As we start thinking about CRUD for entries, we'll want to have a home to put that stuff.

This PR kills the "dashboard" and replaces it with entries. No behavior is changing here, we're just doing a bit of preparation for what is to come.
