Devansh Varshney 048b35b49d chart2: Add UI and basic rendering for Histogram chart 
This commit introduces the structural foundation and user interface for
the new Histogram chart type. The rendering engine gracefully falls
back to plotting the raw values-y input data directly. As a result, the
chart currently renders identically to a standard bar/column chart.

- Adds UI entries in the Chart Type dialog.
- Adds HistogramChart to the view layer, inheriting from BarChart and
forcing a 0-gap width.
