apollo.updateContactSequenceStatus changes selected contacts across sequences in a background job.
automations/stop-apollo-sequence-contacts.automation.ts
contacts and sequences are non-empty reference arrays. mode is "mark_as_finished" | "remove" | "stop". Optional second argument { account } selects the binding. Returns a background-job receipt with jobId, canonical contact and sequence IDs, mode, current progress, and optional batch size. The receipt means Apollo accepted the job, not that every change is already complete.
