sortable function list: click column headers (addr/name/size)

- on_data_table_header_selected sorts the cached function list by the clicked
  column (address / name / size); clicking the same header reverses. Header
  label shows a ▲/▼ arrow. Sorting composes with the active filter.
- pilot suite 41/41.
