Ties the prioritized marketing-send plan (NY HUT -> CT HUF -> D&A -> New
Carrier Startup -> CA MCP) to the existing Listmonk builders
(setup_trucking_campaigns.py creates the drafts + tests;
populate_new_carrier_startup_campaign.py builds the data-targeted New
Carrier audience). Draft/populate/test steps are safe and idempotent;
starting a bulk send is flagged as an irreversible operator-only step.
Cross-references the new fulfillment_status machine and the authorization
e-sign so campaign expectations match fulfillment.
