[AA-759] feat: add admin for the User Celebration Model

* feat: enterprise learner portal access modal

* fix: quality

* fix: remove log.info

The edx-platform codebase already includes quite a few type annotations, but
they were not regularly checked. This may cause problems, when the annotations
themselves include errors (as we found out in some of the learning_sequences
annotations). So here, we add mypy as a dev requirement and introduce a make
command to run mypy regularly. Mypy runs on a very small portion of the total
edx-platform, as configured in mypy.ini. Our hope is that developers will add
more and more modules to this configuration file, until we can eventually run
mypy on the full code base.

See discussion: https://discuss.openedx.org/t/dev-notes-running-mypy-on-edx-platform/4860

[AA-825] feat: add stacked config model for disabling the frontend-app-learnin…g progress page

fix: remap explicit queues for program tasks

Program tasks got moved from tasks.v1.tasks.py to just tasks.py, but
the mapping was never updated.

chore: update edx-proctoring version

This version of the edx-proctoring library includes a fix to a bug in the onboarding status panel. This bug was preventing the appearance of the onboarding panel in a learner's course outline if an onboarding exam in the course was inaccessible to the learner in such a way that the Learning Sequences API did not return schedule information for the sequence. An onboarding exam that is content gated by enrollment track to an enrollment track in which the learner is not enrolled is an example of this. The bug was that the StudentOnboardingStatusView was not taking into account that an inaccessible sequence might not have a schedule.

feat: add `edx.certificate.revoked` event

- build: add script to list installed XBlocks

Story
=====
As an XBlock developer,
I want to know which XBlocks are installed
so I can debug (and know which to add to Advanced Settings in Studio).

Testing
=======
- `make studio-shell`
- `python scripts/xblock/list-installed.py`

Integration
===========
I plan to invoke this from `devstack` (after installing XBlocks).

[refactor] change backfill date task to long running task

Change from a task that spins off multiple other tasks to a single long
running task. This will hopefully be way less heavy when this is ran in
production.

When getting a subsection grade for a user, instead of failing
if the user can't access that subsection,
fallback to the collected structure.

[AA-759] update name of flag in bucketing check

ENABLE_INSTRUCTOR_ANALYTICS was removed in 2015 by bb7ba752

The Pages and Resources view in the Course Autoring MFE is in development and
this flag allows enabling a link to it from the existing Pages view in Studio
using a waffle flag.

* [refactor] Move backfill_date_for_all_course_runs to Tasks.py

In order for celery to register this task, it needs to be in the right
file. duh!

* fix imports

* fix more imports

[MICROBA-1075]
- Adds a new `edx.certificate.revoked` event to the LMS.
- Refactor of our certificate revocation functions in the GeneratedCertificate model.

This new event will be emit when a GeneratedCertificate with the status of `downloadable` is revoked (through the `invalidate(), mark_notpassing(), or mark_unverified() functions). Event will have a `source` field that will allow us how our certificates are being revoked from learners and can be broken down in the following way:
*Invalidate*
- allowlist_removal
- certificate_generation
- certificate_regeneration
- certificate_service
- certificate_invalidation_list
- bulk_certificate_regeneration

*mark_notpassing*
- certificate_generation
- notpassing_signal

*unverified*
- certificate_generation

REVE-52 is merged and mobile
traffic from older app versions is < 5% of the mobile traffic.
Therefore we dont need changes from this PR https://github.com/edx/edx-platform/commit/325fbe4eb28a76b22c238d87c4b90cfb00b9ffb9#diff-c061bf405edf96531766b26cc2bcc2bb3639d851e5d9f844612c2ea57c35e56e

LEARNER-8377

fix: Update the shift dates logic for problems

Even if a learner could technically continue to attempt a problem,
if they didn't have any missed deadlines in the course, we would
never display the ability to shift dates. This corrects that to
not require a missed deadline. The banner on the unit is still gated
by needing a missed deadline.

chore: update edx-proctoring version

* [feat] Management command to populate credentials availability date

This is a command to populate the new CredentialsCertificate model's
available_date for every existing course_run.
