feat(monitoring): dispatch monitoring tasks to desktop via AMQP outbox

Replace SSE /desktop/events with priority AMQP dispatch for monitoring
runs, and add phase1/phase2 infrastructure so desktop workers can lease,
resume, report, skip, and cancel monitoring tasks over the existing
dispatch WebSocket.

- Add monitoring collect outbox worker and phase2 desktop task fields
- Add /desktop/monitoring/tasks/{lease,resume,result,skip,cancel} routes
- Introduce execution-devtools and network-observer on desktop runtime
- Refactor runtime-controller, LoginView, and doubao adapter for the new flow
- Add channelName column to tracking views
