feature request: enhance term enrichment figures

I would be if the figures generated as a result of term enrichment could display extra information, such as the p-values.

Here is an example from the paper [Ontology development and use for cholangiocarcinoma risk factors and predictions: a term enrichment data analysis and machine learning classification](https://link.springer.com/article/10.1186/s13326-025-00345-2) (see figure 4).

The p-values are described in the legend (figure 2).

Locate the term-enrichment figure generation entry point and inspect how the current figures are assembled. Compare the output with the linked examples, then determine how p-values or similar enrichment metadata should appear; done means the generated figures display the requested extra information clearly and consistently.
