Paneles

Panel	Que muestra
DAGs	Lista de DAGs (data_table_cpp_viz). Columna Recent = ultimas 5 runs como puntos (CellRenderer::Dots). Double-click -> abre DAG Detail.
DAG Detail	Header (nombre, desc, schedule) + boton Run Now (POST /api/dags/{name}/run) + tabla recent runs. Double-click run -> Run Detail.
Run Detail	Header (id, status, started/finished) + tabla steps (status/exit/duration) + CollapsingHeader por step con stdout/stderr.
Timeline	Scatter ImPlot. X=tiempo, Y=DAG, color=status. Ventana 15m/1h/6h/24h/7d. Hover -> tooltip con run id + trigger.
Live (WS)	Estado conexion + msgs count + watermarks runs/steps + lista live runs.
Main (diag)	Diagnostico HTTP: boton Fetch + dump raw de g_dags.
