[6.0.x] Refs CVE-2026-4292 -- Isolated new test in AdminViewListEditable.

As originally written, this test interfered with
admin_views.tests.SeleniumTests.test_inline_uuid_pk_add_with_popup.
To fix this, register the new ModelAdmin with a different AdminSite.

Backport of 280256499c5b2d636949f3c8cb52159a8e4c26bb from main.
