Envelope-level access code + send the code in a separate DocuSign email

Today, Access Codes are set per recipient, which gets painful when an envelope has multiple recipients (repetitive setup, easy to miss someone, hard to manage).

Request:

1. Add an envelope-level option: “Require access code for this envelope” → automatically applies to all recipients.
2. Add an option to send the access code in a separate DocuSign system email, so it’s not included in the envelope invitation/email thread (helps when invitations get forwarded).

This would reduce admin effort, improve consistency, and strengthen real-world security.
