Gene page - show gene lists / panels

Gene lists currently shows and it's huge. I think we should make it click to expand

Just above this (as panels are more important than random lists) - we should look up via canonical transcript collections etc - to find gene panels. Would be useful to see what panels have it. (seqauto systems only with panels enabled).

Locate the gene page implementation and the existing gene-list display. Trace how canonical transcript collections and seqauto systems with panels enabled are represented, then define completion as a collapsible gene-list section plus a panel listing above it showing panels that include the gene.
