feat: verify warmup mail that arrives without its verify header, because Microsoft Graph strips custom headers in transit and re-stamps the Message-ID, so every warmup email sent from an Outlook or Microsoft 365 mailbox reached its recipient unmarked, consumed no token, earned no engagement and was filed in the recipient's unibox as ordinary mail; the Graph client now creates the message as a draft and sends that so it can read the internetMessageId Exchange assigned, the consumer records that delivered id on the task and its warmup token alongside the sent subject, and the recipient resolves an unmarked warmup email by delivered Message-ID or by the pending sender/recipient/subject pair
