Scope: write:aml

For a partner that runs the AML check outside Loop. Send a multipart/form-data request
with the file. It's saved in the person's AML section in Loop, not on a Documents tab, and
replaces any AML document they already have. Uploading it counts the person as verified.
Once every seller in a seller group has an AML document, the group's pre-market and
on-the-market sales properties are marked AML verified, with a note, as they are in Loop.

Only for agencies that verify AML by document upload. If the person's team has AML switched
off, or checks AML through MoveButler, the call answers 409 and nothing is saved.

user_id is optional: if supplied it must be a Loop agent in the person's team; if omitted
the first agent in the team is recorded as the uploader.
