Migrate away from django-ckeditor (CKEditor 4 unmaintained)

[Yamgirly]

Background

CKEditor 4 is no longer supported and has unfixed security vulnerabilities. The django-ckeditor package now emits a ckeditor.W001 system check warning about this on startup.

We are currently silencing this warning via SILENCED_SYSTEM_CHECKS = ['ckeditor.W001'] as a stopgap.

Options

• django-ckeditor-5 — drop-in upgrade to CKEditor 5, but note the CKEditor 5 license changed to GPL in 2023 which may or may not be compatible
• Another editor — e.g. Quill, TipTap, or similar
