// meeting CONTENT (title, attendees, notes, color, status, merge) so
// that visible position i ends up holding the i-th tuple from the
// original chronological order.
//
// `orderedIds` is the new visible content order (same set as the day's
// non-cancelled meetings — every visible row must appear exactly once).
// `expectedUpdatedAt` carries each visible meeting's last-known
// `updatedAt` ISO string so the server can detect concurrent edits and
// return 409 `stale_meeting` like the other optimistic-locked routes.
