Pasture: Mobilizon joins

Mobilizon 5.2.4 on a PostGIS of its own (it needs the extension, which the shared Postgres has not got), trusting
Caddy's CA through the bundle mounted over certifi's and castore's files (hackney trusts only those), with geocoding
pointed at a closed local port. scenarios/mobilizon.sh passes its 23 checks: alice follows a group; the event its
organiser makes arrives as an Event with its start, end and located place; comments both ways; the organiser's edit,
closing the comments (PrivaPub then refuses a reply) and deletes of a comment and the event; a group post with its
title; the unfollow; statistics. An event made through Mobilizon's API without options has its comments closed, so
the scenario opens them. No RSVP yet.
