Recompute the VeriFactu hash chain (`huella`) for your company and compare it against the persisted values without mutating data. Returns whether the chain is intact and, if not, the first corrupted record. Rate-limited to 1 request/minute and rejected with 422 `dataset_too_large` for datasets over 50,000 records.
