SvgChartExporter class

Generates a minimal SVG string for simple chart types.

Intended for:

• Server-side chart thumbnails
• PDF embedding (via flutter_svg or webview)
• Email reports

Only covers bar, line, and pie. Complex charts (sankey, treemap) require a full render-to-canvas → PNG pipeline instead.
