Introduce a desktop.task.dispatch topic exchange with per-client routing keys. Tenant-api publishes a task_available frame keyed by target client ID when a publish job is created; every instance binds its own transient queue and forwards to the matching WebSocket (/api/desktop/dispatch) it owns. Desktop-client now prefers this push channel and only falls back to HTTP /lease polling when the socket is down. Also drop admin-web monitoring-plugin remnants and scope the publish modal account list to publish platforms. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
