Pasture: Funkwhale joins, closing wave 1

Funkwhale 2.0.11: the API, a Celery worker with its beat and the front's nginx sharing one volume, on the shared Postgres
and Redis, trusting the pasture's CA through REQUESTS_CA_BUNDLE; fwuser and its OAuth token made by its own tools.
scenarios/funkwhale.sh passes its 16 checks: alice follows a channel, a track uploaded to it arrives as Audio with its
file and duration, its deletion reaches PrivaPub, the unfollow, statistics.
