Module batch_insert 

Issue #582 — Analytics slice 4: BatchInsertEndpoint HTTP support.

Owns the config + durable idempotency receipts that the POST /collections/:name/batch handler uses to:

• reject batches exceeding red.batch.max_rows with 413 BatchTooLarge before any storage work,
• deduplicate requests carrying the same Idempotency-Key within red.batch.idempotency_window_secs, returning the previously committed response body verbatim across process failover,
• report row-level validation failures by index so the caller can pinpoint the row that broke the all-or-nothing commit.

The actual commit + AnalyticsSchemaRegistry validation runs in the handler (server::handlers_entity::handle_batch_insert). This module only owns the pieces that need to be unit-testable without booting a full HTTP server.

Structs

BatchInsertConfig

DurableReceipt
