Pasture: Gancio joins

Gancio 1.28.2 on its own sqlite, its config.json written before the first start (without it Gancio waits in its setup
wizard), trusting Caddy's CA through NODE_EXTRA_CA_CERTS; fediverse replies are kept as event resources. Its one
Application actor publishes the agenda, and scenarios/gancio.sh passes its 17 checks with no change to PrivaPub: the
follow, an event with its start, end and place, a reply kept as a resource, the edit and the deletion, the unfollow,
statistics.
