`signing.envelopes.send`

Send a prepared draft for signature. Each signer receives a private link by email (company signers are asked to sign in Oatmilk); copied recipients are notified. Sequential envelopes notify the next signers only when earlier signers finish. A document that states pay needs its structured pay first, and a job it names must still be in use. A contractor agreement sent to a linked contractor records its job, pay and dates as an update to their terms that takes effect once everyone signs; only one update can wait at a time, and a new title needs a title change first.
