test(docker): a plugin template can take its own name; the overview's assertions follow its new tables (#5299, #5302)

render_plugin_template's first three arguments are positional-only, so the
service page's own `name` reaches the template. The overview names a service
rather than its replica containers, and a stack chip keeps the search it was
clicked under.
