All style sub-objects (title, legend, xAxis, yAxis, dataLabel,
background, border, animation) are guaranteed to exist in Redux.
This fixes:
- Style config panels showing blank (returned null for missing fields)
- Style changes not applying (updateStyle now deep-merges sub-objects)
- Color palette changes not persisting

- ensureStyle: handle empty colors array (use defaults)
- barOptionBuilder: set option.color = style.colors globally
so ECharts auto-assigns palette colors to all series
- Changing palette in style panel now updates chart colors immediately

When a field is dragged to the 'label' slot, data labels are
automatically shown on top of each bar with the value.

Dragging a field to the 'color' slot now creates separate colored bars
per category value, with auto-generated legend. Also aggregates
multiple rows per category (sum) instead of taking first match only.

Root cause: backend returns minimal style object without title/legend/axis
sub-objects, causing TypeError 'Cannot read properties of undefined'.
Fix: normalize style with full defaults at the builder entry point,
protecting ALL chart type builders uniformly.
Also fix antd deprecation warnings (destroyOnClose -> destroyOnHidden).

When creating a chart, automatically assign first text column to X axis
and first number column to Y axis (varies by chart type).
Charts now show data immediately instead of blank.

- All 4 API clients now consistently use /api/v1/ prefix on all routes
- ChartRenderer fills missing style fields with defaults to prevent
undefined property crashes when backend returns minimal style
- KPICard uses safe defaults for background/border/title

a chart instance on the backend and add it to the canvas.

WidthProvider is not available during SSR. Use dynamic import
inside useEffect to load it only on the client side.
