fix: redirect to plugins page when no plugins enabled on empty dashboard

When an empty editable dashboard is viewed, check if any plugins are
enabled for the current server. If none are enabled, redirect to the
plugins settings page so the user can enable plugins first (which
registers widgets). Only redirect to the dashboard editor with the
widget palette open when plugins are already enabled.

Closes #6
