For a firm: bind and unbind on the team table as it stands, and send it with confirm

The binds, in order, then the unbinds, laid on the table as it stands. A bind is a MOVE: the member is taken off whichever employee held them. While the connector is pending_mapping, a row nobody bound takes the email pre-match; on a connected firm it stays as it is. An employee the practice system does not have is a 422. Without confirm the answer is the whole table it would send and nothing is written; with it the table goes through PUT /v1/connector/team's own code and the answer carries the connector after the confirmation and its sync. 404 with no connector, or for a kind whose identity is a per-user sign-in. Audited as connector.team either way, with confirm.
