Submit a batch of settlement operations (streaming NDJSON)
Accepts newline-delimited JSON (application/x-ndjson). Each line is one operation, validated and created through the same pipeline as POST /v1/operations, grouped under one generated batchId. Processing is synchronous and streamed line by line; one bad line is rejected with a per-line error without aborting the batch. The line count is capped by a configured maximum; exceeding it returns 413. Optionally idempotent via the Idempotency-Key header.

Headers
Idempotency key for safe retries of the whole batch
