Pasture: Vernissage 1.43.0

Vernissage joins the pasture on SQLite with its queues on the shared Redis; scenarios/vernissage.sh: follows both ways,
a photo with its alt text, likes, boosts and comments both ways, a deletion, the unfollow and statistics: 19 checks,
with no change to PrivaPub.

+# Vernissage 1.43.0: photo sharing in Swift (Vapor), Pixelfed's neighbour: every top-level post carries photos with
+# their EXIF (camera, lens, film...), comments thread under them. Its image on SQLite with local storage in its own
+# volume and its queues on the shared Redis (database 0, the last free one: without queues it federates nothing), as
+# vernissage.test; its TLS client reads the system's roots, over which the pasture's bundle goes. It seeds an
+# admin (admin/admin) whose token comes from its login API.
