- Why:
- dashboard tiles failed with "Item with key 'echarts_bar' is not registered".
- existing slice query_context stayed stale after config updates.
- What:
- switch Top Pages and Data Quality Summary from \'echarts_bar\' to \'dist_bar\'.
- use \'groupby\' for categorical bar charts and sync this into query_context.
- keep dashboard export config aligned with runtime chart definitions.
- Check:
- python3 -m py_compile superset/create_dashboard.py
- docker compose exec -T superset python /app/superset_init/create_dashboard.py
- DB check for slices 9/10: viz_type=form_data=query_context set to dist_bar
