Get an envelope's audit trail

The signing evidence for one envelope, oldest first, one page at a time. page is 1-based, limit defaults to 20 and is capped at 100, and the response carries the standard pagination block. Rows with the same timestamp are ordered by their internal sequence, so walking a stable trail does not repeat or skip an entry.

Because the trail names every signer and everything they did, it costs both envelopes:read and account:read. Either grant alone is weaker than the answer.

Actions taken through a service credential are recorded with actorType: "service" and actorName set to the credential's agent identity; signer activity is actorType: "signer"; dashboard activity is user; scheduled jobs are system. metadata is the parsed JSON the action recorded, or null.

Four events are recorded about a recipient rather than by an actor: signer.notified, signer.reminder_sent, envelope.cc_delivered and envelope.cc_delivery_failed. Those rows carry the person written to as metadata.recipientName and metadata.recipientEmail, and their actor fields are null unless a person triggered the send, in which case the actor is that person. Never read a recipient out of actorEmail.
