Dumpdata - does not work (for Meagen)

[Stormheg]

Missing revisions cause the dump to not restore!

[Stormheg]

Cleaning up revisions before dumping using manage.py purge_revisions and including it in the dump helps, but then we get stuck on foreign key references to users that are not part of the dump...

Pull Request Overview

This pull request introduces a management command to load initial data by wiping out existing data in several models and then reloading from a fixture to address issues with dumpdata not restoring revisions.

• Clears existing data in models including Site, Page, Permission, Group, and ContentType.
• Calls the loaddata command to repopulate the database with initial data.

Deleting all ContentType objects may remove essential system metadata that Django uses for content type management, potentially causing downstream issues. Consider targeting only specific ContentType objects that need to be reset or ensure a mechanism to properly regenerate them.

Suggested change

	ContentType.objects.all().delete()
	ContentType.objects.filter(model__in=['page', 'site', 'permission', 'group']).delete()
