feat: upgrade edx-enterprise to 8.9.0

[pbitla-sonata]

Description

Bumps the manually-managed edx-enterprise pin from 8.7.2 to 8.9.0 and recompiles the
affected requirements files.

Per the comment in requirements/constraints.txt, this package is deliberately excluded from
automated upgrades so the owning team controls its rollout, so this is a manual bump.

This spans two upstream releases:

• 8.8.0 — feat: add pipeline steps for logistration filters
• 8.9.0 — feat: add non-production portal banner configuration

The 8.9.0 change adds a Non-production enterprise customer type. Assigning it to an
EnterpriseCustomer sets the new read-only show_non_production_banner property, which is
exposed on the enterprise customer API serializer so the administrator and learner portals can
render a banner indicating the portal is not production.

Requirements diff

5 files, one line each, all edx-enterprise==8.7.2 → edx-enterprise==8.9.0:

• requirements/constraints.txt
• requirements/edx/base.txt
• requirements/edx/development.txt
• requirements/edx/doc.txt
• requirements/edx/testing.txt

No transitive dependency churn: 8.7.2 and 8.9.0 declare the same 48 Requires-Dist entries, so
make compile-requirements (run under Python 3.12, matching the existing file headers) produces
only the pinned version line in each file.

Affected user roles

Operator / Administrator (configures the customer type) and Learner (sees the banner). There are
no UI changes in this repo — the banner is rendered by the portal MFEs off the API field.

Testing instructions

1. Deploy this branch and run migrations:

   ./manage.py lms migrate enterprise
   

   Exactly two new migrations should apply:

   • enterprise.0250_alter_enterprisecustomer_customer_type_and_more
   • enterprise.0251_add_non_production_customer_type

2. Confirm the data migration created the customer type:

   ./manage.py lms shell -c "from enterprise.models import EnterpriseCustomerType; \
     print(EnterpriseCustomerType.objects.filter(name='Non-production').exists())"
   

   Expect True.

3. In Django admin, edit an EnterpriseCustomer and set Customer Type to Non-production.

4. Hit the enterprise customer API and confirm show_non_production_banner is true for that
   customer and false for customers with any other type.

5. Regression check: existing enterprise customers keep their current customer type and report
   show_non_production_banner: false.

Other information

Migrations. 8.8.0 introduces no migrations. 8.9.0 ships two in the enterprise app:

• 0250 is a pair of AlterField calls that change only the help_text on customer_type
  (and its historical model). No schema impact.
• 0251 is a RunPython that creates the Non-production EnterpriseCustomerType row.
