Clear a queued roadmap item's horizon pin (now/next/later → none). A horizon pin dominates the queue sort, so `reorder_roadmap` cannot move a pinned item out of its band — a stale `now` pin on a delivered/duplicate item clogs the front of the queue. This unpins it and reprices the queue so the item follows plain priority order again (and reorder_roadmap can then move it). Only queued items carry a settable pin (in-flight / shipped items derive theirs), so this refuses (422) on a non-queued item — use cancel_roadmap_item to close a delivered item. Returns {id, previous_pin, horizon_pin, next_step}.
