Django 6

[ajslater]

Update Codex for Django 6.

Codex's previous minimum python version was 3.10. Django 6 requires python 3.12.

Python 3.11:

• Don't use tomli versions of coverage & radon
• use itertools.batched() instead of my own batching.

Python 3.12:

• use typing instead of typing_extensions
• use Path.walk() instead of os.walk()
• use datetime.UTC instead of datetime.timezone.utc

Django 6

• Use Django 6 Content Security Policy
  • Use SpectacularSwaggerSplitView() to work with content policy
• Use order_by in JsonGroupArray and GroupConcat
