Add Numerical Comparison Operators for Custom Dimensions in Matomo UI

[goochj03]

Currently, Matomo allows segmentation of custom dimensions in the UI using string-based operators such as "contains," "starts with," and "equals."

However, for custom dimensions storing numerical data, segmentation options like <, >, <=, and >= are unavailable in the UI.

e.g.
&segment=dimension11>2513450410

These numerical comparisons are supported when querying via the LIVE API, demonstrating that the backend supports this functionality.

This feature request proposes extending the UI to include numerical comparison operators for custom dimensions to ensure consistency and improve usability.
