R5 the server's own settings in decePub: instance, rules, announcements, relays, media limits, the staff's log, About

Administration's Pleroma placeholders give way to real sections: Instance (title, descriptions, contact, thumbnail,
privacy policy, terms, the weekly activity), Rules, Announcements, Relays, Media limits and the Moderation log, next to
Reports, blocked servers (now published or obfuscated), statistics and backups; moderators see Reports and the log. Every
save sends the whole settings form built from the latest read, since PrivaPub replaces what it carries. /about shows the
server's documents to anyone. The report dialog picks the rules a violation breaks, and reports show them. Announcements
show above the feed tabs, dismissed and reacted to, live from the user stream. Login names the server.
