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

A singleton ServerSettings (title, descriptions, contact, thumbnail, privacy policy, terms, rules, relays, media
overrides, PublishActivity), cached by InstanceSettings and read by the instance API, NodeInfo, the instance actor, the
web pages and the mailer; its defaults are the old literals, so nothing changes until an administrator edits.
/clientapi/admin/settings (and /thumbnail), /announcements, /relays for administrators; /clientapi/moderator/log, the
staff's log (AdminAction, written by domain blocks, backups, settings and the CLI; no IP, never a root paired with its
personas). The Mastodon API's rules, extended description, privacy policy, terms of service, domain blocks (Published,
Obfuscate), announcements (dismiss, reactions, streaming) and activity (only when published). Reports carry rule ids.
Media overrides clamped to hard caps. Relays named by the settings reconcile next to the configured ones.

Verified: interop.sh instance accounts relay with mastodon, relay, aoderelay and mailpit, 119 passed.
