Check an email channel's DNS records
POST /api/channels/{channelId}/dns/probe
Looks up the DNS records an email channel’s inbound_mode asks to publish (config.dns_records) and reports each one’s state: the check check_channel_setup runs over the tenant MCP. A mode with no records to publish answers an empty list with reason. Six checks a minute per channel. Requires the channels:read scope; a key restricted to a brand or workspace checks the channels of the workspaces its restriction covers.
