Attach Revision Integrations

Attach one or more integrations to an agent revision. To pin specific connections after attachment, use pinRevisionIntegrationConnection. IMPORTANT for the case-queue-producer and case-queue-consumer integrations: attaching the integration alone is NOT enough — the slot points at no queue and will fail at runtime until you link at least one queue with replaceRevisionIntegrationQueues. After wiring up, call getRevisionCaseQueueSetup to confirm every case-queue slot has linked_queue_count > 0 before starting work.
