Add Management Command for Copying and Translating Pages Across Locales

[nickAalst]

Summary

This PR introduces a new Django management command to automate the process of copying Wagtail pages from a source locale to all other locales and applying machine translation where applicable. The command allows exclusions of specific models and supports a dry-run mode for testing.

Command Usage

python manage.py copy_and_translate_pages <language_code> [<exclude_model1> <exclude_model2> ...] [--dry-run]

• <language_code>: The source language code from which pages should be copied.
• <exclude_model1> <exclude_model2> ...: Optional list of model names to exclude from translation.
• --dry-run: Runs the command without making any actual changes (useful for testing).

Example run

python manage.py copy_and_translate_pages en BlogPost EventPage

or for testing

python manage.py copy_and_translate_pages en BlogPost EventPage --dry-run

Thank, would be good to add some tests. I hope to get some time next week to review this.

off the top of my head, I'd like to make the exclude list a param --exclude ... rather than exclude_model, exclude_model2

@zerolab I've added some tests. Let me know if you'd like more.

I also renamed exclude_models to --exclude
