refactor: move config badges inline, fix trace config from server

- Render hasTrace/hasTap/status badges inside the node card in both
  raw diagram and overlay modes (consistent positioning)
- Pulse only on trace badge in overlay mode when hasTraceData is true
- Fix nodeConfigs to read tracedProcessors from appConfig instead of
  never-synced tracing store
