Add drag reorder of VCF samples to VCF trio display. Also fixes bug in haplotype sort that I didn't discover until adding drag reorder. Sometimes when sorting haplotypes it is the case that the initial best match to a child allele is the same for each parent. Previously I would just advance the first drawn parent to the next best match but now I also check whether advancing the first drawn is actually the best idea and potentially advance the other parent instead, refs #25582

             the solution is likewise noted there, grab the offset of a table cell in the row - the firstChild.
             note that firefox will return a text node as a first child, so designing a more thorough
