[FIX] charts: hierarchical charts should show formatted labels instead of raw

Before this commit:
- Hierarchical charts interpret datasets as labels and the last column
  as values. dataset cells were read as raw values, which is correct for
  other charts but incorrect here because these values are rendered as labels.
- As a result, formatted values were displayed incorrectly in charts
  like Sunburst and Treemap.

After this commit:
- Dataset columns used as labels now use formatted cell values instead
  of raw values, ensuring dates and other formatted types display
  correctly in hierarchical charts.
