CHW-4826 BulkActionTooLarge

bulk action exceeded the maximum allowed items per request; split into smaller batches

Default message: bulk action exceeded the maximum allowed items per request; split into smaller batches
HTTP status: 400 (client)

Problem. POST /api/actions/bulk was rejected. Cause. The items[] array exceeded the server-enforced cap. Fix. Split into smaller batches; the cap is documented at the route. HTTP 400.
