• p or adj.p ?
• should it be toggled based on checkboxes?

It looks like only relies on the significant column, which is not appropriate, should be based on the actual p-value column since users can toggle p val and adj,p. https://github.com/MonashProteomics/FragPipe-Analyst/blob/ffb3a9d7f83eaa2a9b5b0f350c599413fd34de1a/R/volcano_function.R#L385-L390
