Introduce backpressure mechanism for the Elasticsearch backend

Better guidance for misconfigured or unconfigured projection/loading in Standalone pojo mapper

Links to relevant documentation in exceptions/logs

Document that concurrent indexing is unsafe without outbox-polling

Optimistic concurrency control
