Settings, Administration and conversations; threads that fill in

Settings, which held only the theme, now belong to the persona too:
- its profile (update_credentials, a new PATCH in IHttpService): pictures,
  name, biography and fields as written, locked, bot, discoverable,
  indexable, and how its posts start (visibility, language, sensitive
  media, who may quote them); the composer starts at that visibility;
- the root's personas, each used in turn, and a new one made;
- the accounts it muted or blocked and the servers it blocked, each undone
  there, a server blocked from a pasted address or handle;
- its follows, lists, blocks, mutes, blocked servers and bookmarks exported
  and imported as the CSV files Mastodon writes (PortabilityService): an
  import resolves each row through PrivaPub, one at a time, and can stop.

Administration opens to moderators: reports, resolved there; and for
administrators the servers blocked for everyone and the federation
statistics (traffic by server, delivery success and latency, the crawler).

The Direct tab pages conversations, badges the unread ones, and a card
marks one read or takes it off the list; opening one reads it.

A remote thread is read again 4 and 15 seconds after it opens, since
PrivaPub then fetches the replies its servers hold. A thread its
community locked shows a lock instead of a reply button, reactions stay
visible below a content warning, and a searched handle opens its
account's profile whatever else matched.

The e2e tests cover each: the profile saved and read back, a persona made,
servers blocked and imported, follows exported, an instance block and the
statistics as the pasture's admin, a conversation read and removed, and a
reply only Mastodon held appearing in its thread.
