улучшить observability и документацию outbox

- обновить README с текущим Kafka, DB, outbox и scaling flow
- расширить логи listener, ingestion, publisher и outbox worker
- не логировать raw payload и outbox payload
- закрыть test controller явным property
- добавить Micrometer counters для ingestion и outbox outcomes
- сохранить listener flow, payload contract и delivery semantics без изменений
