database_query is a module: it opens query_file on the host it runs on. In swarm the task is delegated to the stack host, which has no repo checkout at role_path, so query_file is not found. A new action plugin (same name auto-wraps the module) reads query_file on the controller and passes the SQL as 'query', so every role's query_file: works in both compose and swarm with no call-site changes. Reverts the per-call-site fider workaround in favour of this root fix, which also covers mattermost, odoo, openproject and pixelfed.
