Replaces ugettext with ugettext_lazy in the dashboard-related files

While most files correctly import ugettext_lazy, some are importing ugettext instead.
This is causing some parts of the dashboard to not translate correctly when a user
switches languages. The core cause of this is because ugettext will translate the
string once when the django application starts. ugettext_lazy will translate when the
string is retrieved.
