r/nextcloud: Configure Memories app

The [Memories] app for Nextcloud provides a better user interface and
more features than the built-in Photos app.  The latter seems to be
somewhat broken recently (timeline stops in June 2024, even though there
are more recent photos available), so we're trying out Memories (and
Recognize for facial recognition).
