Fixed display of verification deadline on course form

Displaying average paid order cost on dashboard

The HTML5 standard only supports datetime-local fields. We need UTC always. We work around this by removing the timezone component when parsing data from the server, and restoring the timezone component when writing back to the server.

  This workaround is already in place for the seat expiration/upgrade deadline. This commit implements the behavior for the course verification deadline.

XCOM-520

Given that most of our orders are free orders, the current "average order cost" value is mostly useless. This commit adds an additional row to the table—average paid order cost—that will be more useful.

XCOM-558

Added support for the display and editing of audit modes

Users can interact with existing audit seats, but will not be able to create new ones.

XCOM-541

Strip whitespace from course names during migration

Update outdated slugs for existing products
