Research direction

Start with the CLI export and import steps described in the issue, reproducing the failure between the Docker and NixOS instances. Check the PostgreSQL and PHP 8.3 configurations alongside the activated user_migration app; done means importing the CLI export completes without the “Failed to get migrators versions” error.
