Pivot table zero sort

[ericokuma]

Fixes ENG-1038 by ensuring numeric-like dimension values in pivot table column axes are sorted numerically (e.g., 0 appears before 1, not between 5 and 6).

Previously, these values were treated as strings, leading to incorrect ordering. This change introduces a utility to numerically sort column dimension axes only when all values are numeric-like, preserving existing behavior for categorical dimensions and row sorting.
