a send form for SendOff, and no receiving one

/sendoff — pick files, pick one of your own machines or a person who has allowed
you, send. The consent list sits on the same screen rather than in settings,
because the two questions arrive together: the first time somebody opens this and
finds nobody to send to, the reason is that consent runs the other way, and the
answer has to be visible where the question was asked.

There is deliberately no received view. Files land in Documents/SendOff/ inside
the recipient's own tree, so the file browser already IS the inbox — a second view
of the same directory would be a worse copy of one that works, kept in sync by
hand.

Two details worth keeping. The file input resets its value after every pick, or
choosing the same file twice in a row does nothing, because `change` does not fire
on an unchanged value. And a send clears the files but keeps the target, since
several batches to the same place is the common second action and re-picking it
each time is the sort of small tax that stops somebody using a thing.

The multipart goes through `client.post`, which already recognises a FormData and
drops the JSON content-type so the browser picks the boundary. That was the only
thing making this look like it needed a raw fetch, and a raw fetch would have
carried its own copy of the token resolution — which is a chain of seven sources.
