[feature] Public list of suspended domains (#1362)

* basic rendered domain blocklist (unauthenticated!)

* style basic domain block list

* better formatting for domain blocklist

* add opt-in config option for showing suspended domains

* format/linter

* re-use InstancePeersGet for web-accessible domain blocklist

* reword explanation, border styling

* always attach blocklist handler, update error message

* domain blocklist error message grammar

+			servers.
+			This extends to subdomains, so an entry for 'example.com' includes 'social.example.com' as well.
