/**
 * v1 of bulk operations runs synchronously through per-entity bulk
 * endpoints (see `/api/v1/interests/bulk`) — a per-row loop, capped at
 * the page size (100). The synchronous path gives the user instant
 * feedback and a per-row failure list, which the queue can't.
 *
 * This worker remains here for genuinely-async cases (CSV imports,
 * port-wide migrations, bulk emails to >100 recipients) where the
 * caller polls for completion. Currently no producer enqueues to this
 * queue — add producers as those use cases surface.
