AA-289: rewrite how course updates behave when dismissed

Adding brand-edx.org as a dependency to edx-platform

Set expiration_date field in IDVerificationAttempt model

Previously, dismissing one course update would disable all future
updates. But that feels a bit limiting.

Instead, these are the new rules:
- If the newest update has not been dismissed yet, it gets displayed.
- If the newest update has been dismissed, we display nothing.
- Editing the newest update will cause it to be displayed again.
- New updates get displayed, even if previous updates were dismissed.

This commit includes a light refactoring and addition of some utility
methods to help manage the above.

It also notes that the learning MFE does not use the "latest_update"
waffle option, which controls the labeling of the update message.

ENT-3680: Updated edx-enterprise version and only set user language preference on signup if it does not already exist.

Fix certificate sass assets collection for comprehensive themes

When rolling out #25477, we dropped hundreds of email activation
tasks due to the renaming of student.send_activation_email
to common.djangoapps.student.send_activation_email,
and lost more when we rolled that PR back.
This happens because of blue/green deployment:
old workers are still online for a while after deploying,
so there is a period of time when the task names are mismatched.

To prevent this from happening again, this will make
it so the import changes don't change the names of
any of the Celery tasks.
