📤 Export Widget Now Reflects Ad-hoc Interactions

Canvas dashboard widget exports now reflect ad-hoc interactions you've applied on screen - so what you export is exactly what you see.

Previously, exporting a chart after applying ad-hoc changes would revert to the original unmodified data. To get an accurate export, users had to switch to Explore mode and manually reapply every interaction. Now the export captures the current on-screen state directly - no workaround needed.

This applies to all supported ad-hoc interactions: block-level filters, date drill-downs, and breakdown dimension changes. Both data exports (CSV/Excel) and image exports (PNG/JPEG/SVG/PDF) are covered. No UI changes - same export action, correct output.
