Resume paused or completed campaign

Resume a campaign with status paused or completed (same behavior as the dashboard's Resume button).

paused: the campaign is re-activated. Leads paused with the campaign rejoin the sequence.
completed: allowed only when there is something left to send, i.e. leads added after the campaign finished, or (with reEngageCompleted: true) finished leads that have new sequence steps. Adding leads to a completed campaign does not restart it by itself; call this endpoint afterwards.

Resuming requires an active subscription with remaining email quota, at least one sequence step, at least one active sending-enabled mailbox, and at least one lead. Stale scheduled send times are cleared so sending restarts at the normal pace.
