Adding new functionality is going to require running this command
on all courses, not just ones that have it missing.

* fix: six was being used without being imported

Removed usage of the python library six from module. This is fixing an error where the python library six is used in a module without being imported. Multiple PRs merging around same time caused this conflict.

replace six with str

Added custom for SSO auth entries to monitor which auth entries are

AA-213: create progress tab mfe waffle flag

The Learning MFE had a bug where instructors selecting
'View As: Audit' would find themselves redirected to the
'Enroll Now' page. This was because the Courseware API,
 which powers the MFE, checked courseware access *after*
setting up masquerading--so, instead of checking whether
the instructor had access to view the course, we checked
whether some arbitrary un-enrolled learner would have
access to the course (the answer is generally No).

We fix this by doing what the Legacy courseware index
does: calculate courseware access *before* setting up
masquerading.

[TSD] add annotations for AUTOMATIC_AUTH_FOR_TESTING feature flag

In https://github.com/edx/edx-platform/pull/25955 `HiddenDescriptor`
(which was a subclass of `RawDescriptor` with a custom `student_view()`)
was converted to an XBlock. It is used as the `default_class` by the
`CachingDescriptorSystem` classes. However `RawDescriptor` is still
being used by `XMLModuleStore`. This has been replaced by
`HiddenDescriptor` as well.

[TSD] Added annotation for ALLOW_HIDING_DISCUSSION_TAB feature flag

The Studio UI prevents you from creating a Section or Subsection
with no title (display_name). But OLX import allows you to bypass
these checks and create Sections ("chapter" tag) and Subsections
("sequential" tag) without display_name information specified in
the XML. When this happens, Studio and the LMS fall back to using
the url_name (the last part of the UsageKey) as a title, using the
display_name_with_default method.

This usually works, because url_names are derived from the import
file name, and if you're hand-editing a course in XML, your file
names are probably more intelligible than Mongo object IDs. In any
case, this commit updates get_outline_from_modulestore to match the
behavior of Studio and the LMS with respect to this situation.

This is part of the course outlines backfill rollout. TNL-8056
