docs(architecture): replace NATS JetStream with RabbitMQ for job dispatch
Switch the durable ingestion/maintenance job-dispatch broker decision from NATS JetStream to RabbitMQ (aio-pika), rewriting ADR-0014 and propagating the terminology change through ADR-0015, ADR-0016, and the ingestion vertical-slice plan. Adds aio-pika as a runtime dependency. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
