Pasture: Smithereen 1.0.3, and failed server descriptions retried

Smithereen joins the pasture (tools/pasture/peers/smithereen.sh): its image on the shared MySQL, with imgproxy and a
file server behind Caddy, a JDK trust store with the pasture's CA, accounts from its signup form, and a password grant
for a local application. scenarios/smithereen.sh drives its VKontakte-like API: friends as mutual follows, wall posts,
comments, likes, reposts (quotes there), polls, edits, deletions, private messages, the unfollow and statistics, 30
checks. A post on someone else's wall never reaches PrivaPub, since Smithereen sends it only to servers whose actors
publish a wall: G-0009, waiting for the owner.

PrivaPub: a server description that failed (Smithereen serves no NodeInfo until it has a description) frees its week,
so the server's next arrival asks again instead of a week later.

The shared Postgres takes 400 connections: at 100 the village seed ran it dry (Sharkey's API answered 500, Misskey
dropped deliveries). The seeder records a follow that stands from an earlier seed when the step itself fails, so the
checker no longer expects that follower to see nothing.
