A persona's archive: exported in Mastodon's layout, imported without telling anyone

A root exports one of its personas (a job) as Mastodon's account archive, so other servers' importers read it: the
actor with its public key only, its own posts and boosts with their media, likes, bookmarks and Mastodon's CSV files,
plus PrivaPub's filters, followed hashtags, notification policy, pins, scheduled and located posts; nothing of its root,
its siblings, its keys or anyone's token. A ticket link downloads it, for a week.

An archive (PrivaPub's or Mastodon's) uploaded in pieces is imported into a persona in a job, the parts the root picks,
with progress and a stop. SafeArchive refuses links, escaping paths, duplicates, bombs and oversized items, and reads the
outbox one item at a time. Imported posts are delivered to no one, put in no home and notify nobody, yet show on the
profile, outbox, hashtags and search; back home a post keeps its id, from another actor it gets one of its date and
ImportedFromURI, so importing twice changes nothing. Relationships go through the existing services; located, scheduled
and likes only when asked; followers never.

tools/pasture/scenarios/persona-archive.sh imports mastouser's real Mastodon archive (156 posts, 24 pictures) into a
persona Mastodon follows: Mastodon receives none of it, and a second import changes nothing.
