Add edX Django Rest Framework Extensions CSRF App URLS to Studio

BUG: fixes for front end work and to align with data requirements.

The Demographics CTA is used to ask users to respond to the optional
questions. This API and model support the API being dismissed by the
user so they are not bothered by it.

This PR updates the track_ecommerce_events.js to allow imports into webpacked code & 
adds upsell tracking to the course upgrade buttons on the program dashboard. We are doing this so we have a better understanding of when users are clicking our upsell links.

These are expensive, read-only web requests. Unfortunately,
middleware adds writes, and we currently run with view-level
transactions enabled by default. Holding those long transactions
open has caused extra load on the database and been our largest
sources of django.db.utils:OperationError exceptions.

This has been particularly noticeable as we start deploying the
new Courseware MFE, which uses the BlocksInCourseView more
frequently.
