fix: move Foreign-Flagged Nodes list above the unscoped-relay table

Reordered so the node list (what's actually accumulating right now,
worth checking back on) comes first, with the unscoped-relay-volume
table — the part that needs more data to be interesting — below it.
Added a heading to the relay table for symmetry with the new
sub-heading above it.
