Sends to people subscribed to the newsletter's list, now or at sendAt (ISO time). Pending and unsubscribed people are skipped. When an assistant (an MCP connection) calls this, it answers 202 with status: needs_approval and a link; a person approves it in Sessionboard. Requires write:marketing; refused for a key restricted to particular events. Also at POST /v1/marketing/newsletter/issues/{issueId}/schedule.
