* feat: Adds a new discussion topic configuration mechanism

The new discussion configuration system links discussion topics directly to the course structure. This change adds a new task that sends a discussion update signal if there are any changes to the course. This signal includes all the context needed to update the configuration of the course.

The handler for this new event will create a new entry for each unit that needs a topic in the database. In the future this will be used to see the topics in the course.

feat!: [BD-13] Deprecate ModuleSystem.render_template

When signing in from the LMS, the authentication request succeeds but
the user was never redirected to the dashboard. This is because of a
js error:

    Uncaught TypeError: userCookie is null
        userFromEdxUserCookie
        http://maple.openedx.overhang.io:8000/static/js/student_account/utils.js:32

The error comes from the fact that the util.js code ignores the
EDXAPP_EDXMKTG_USER_INFO_COOKIE_NAME setting name. Instead the cookie
name is abritrarily prefixed by "stage-" or "prod-" depending on the
hostname. This seems to be primarily motivated by the definition of
edX.org staging/prod environment hostnames :-(

To resolve this issue, we decided that the actual cookie name was not so
important. Instead, the js code needs to not crash even when the cookie
is absent.

fix: fix issues with LANGUAGE_CODE for legacy UI [BB-4823] [OSPR-6196]

chore: upgrade edx-proctoring to 4.7.0

feat: only show IDV panel until honor code replaces it

from test code.

from block code.

in favor of the added MakoSystem render_template method.

Related changes:
* Adds the MakoService to the StudioEditModuleRuntime,
  PreviewModuleSystem, LmsModuleSystem, and XBlockRuntime
* MakoService constructor takes a `namespace_prefix` string, so that the
  CMS PreviewModuleSystem can render to LMS templates, without needing
  the special render_from_lms helper method.
* ModuleSystem.render_template becomes a read-only property, so the
  constructor calls and test module systems are updated accordingly.
* Adds tests for the MakoService and module system shims.

When side-wide language is set via LANGUAGE_CODE site configuration,
some elements of legacy UI still use the language set in user
preferences (or None, which fallsback to 'en' if nothing is set in
preferences). The expectation is that everything should be translated to
the language which is set in the site configuration.

In legacy UI (i.e. templates) the code of the current language sometimes
is needed, and in these cases `user_language` variable from the context
is used. The value for that variable is inserted via context processor,
which takes the value from the user preferences.

The solution modifies the context processor to check if there is a
language set in site configuration, and if there is, send that value,
instead of whatever value there was in user peferences.

the integrity flag is a course waffle flag so until it's on for
everyone this will not be triggered - that's OK and expected
