**INTERNAL USE ONLY — invoked by `service-de-headless-channel-configure`.** Insert an Enhanced messaging `MessagingChannel` (plus child `MessagingChannelUsage` as a free side-effect) of any type — WhatsApp, LINE, Apple Business Chat, Facebook, or SMS. Given a `{MESSAGE_TYPE}` and its inputs, runs the shared preflight → Connect-insert → verify flow, branching only where a type differs.
