Docker: add a Compose stack manager (Containers | Stacks toggle): list stacks in a stacks folder (default /opt/stacks) plus projects found via compose ls, create/edit compose.yaml and .env in an editor (validated with compose config), deploy/stop/restart/down/pull/logs/delete in terminal tabs, clone stacks from Git and git pull + redeploy, app templates in Portainer format (default Lissy93/portainer-templates: container templates are converted to compose, stack templates loaded from GitHub), "Set up folder" makes the stacks folder writable for the SSH user
