fix(plane): clear network false positive and restore canary metadata

- Reword two docker-compose comments so the literal string
  "dokploy-network" no longer appears. The compose never declared the
  network manually (Dokploy attaches it automatically); the automated
  template check was tripping on the comment text alone.
- meta.json: keep canary's richer description and tags
  (kanban, project-management), bumping only the version to v1.3.1.

Deploy-verified on a test Dokploy instance: full stack booted in 465s
and proxy:80 answered HTTP 200 with the Plane landing page.
