fix(config): edge cases in models.yaml migration
When running the configurator, the `legacy_models_conf_path` was stripped when saving the config file. Then the migration logic didn't fire correctly, and the custom models.yaml paths weren't migrated into the db. - Rework the logic to migrate this path by adding it to the config object as a normal field that is not excluded from serialization. - Rearrange the models.yaml migration logic to remove the legacy path after migrating, then write the config file. This way, the legacy path doesn't stick around. - Move the schema version into the config object. - Back up the config file before attempting migration. - Add tests to cover this edge case
