Removed the /v1/drafts, /v1/scheduled-emails, and /v1/unsubscribers endpoints. The behavior of all three endpoints have been subsumed into /v1/emails and /v1/subscribers:

• you can create (or list) drafts by specifying status='draft'
• you can create (or list) scheduled emails by specifying status='scheduled'
• you can list unsubscribers by specifying type='unsubscribed' (Note: this field was renamed from subscriber_type to type in 2024-08-01)
