## Summary
This PR adds support for **stacked grouped bar charts** in Apache Superset's
ECharts MixedTimeseries plugin.
### Before
- Charts support either grouping OR stacking, not both simultaneously
### After
- Charts can have bars that are **grouped (side-by-side) AND stacked (on top
of each other)**
- Example: Display "User Stories" and "Bugs" grouped by sprint, with "Bugs"
stacked by priority (P1 vs P2/P3)
### Changes
1. **`transformers.ts`**: Added `stackGroup` parameter to `transformSeries()`
- When provided, it becomes the base stack ID for grouped stacks
- Allows multiple grouped series to each have their own stack
2. **`transformProps.ts`**: Auto-detects grouped+stacked scenarios
- When multiple groupby dimensions exist, first dimension → stackGroup
- Remaining dimensions → stacked within each group
### Testing Instructions
1. Create a chart with MixedTimeseries/Bar type
2. Add 2+ groupby dimensions (e.g., "Category", "Priority")
3. Enable stacking
4. Bars should group by first dimension, stack by remaining dimensions
