OLX export: Reverted url_name from a constant to course run

closes CRI-102
closes OSPR-2570

Escape validation error messages on reset password page.

- New exported courses include course run information in:
  - `url_name` of root course node
  - file name of root node in course folder
  - root key name in policy.json
  - directory name inside policies folder

- when imported via management command, the OLX will overwrite an
available existing course with the same course key (i.e. same org,
course number and course run)
  - if there is no matching course, one will be created

- when imported via the studio web ui (or import API), the OLX will
replace the current course (no change in behavior)

- courses exported with this commit have been tested to import via
management command and studio web UI in hawthorn and ginkgo releases.
They should also work in prior releases, but have not been tested.
