A record's dialog showed its route only as a text line; add the fan-lane braille
graph above it so a walk's shape reads at a glance — us starred at both ends,
each relay marked and labelled by its first hash byte, the same presentation the
Message paths dialog draws a delivery with.
Extract that presentation into widgets.route_graph_style() — the glyph/label/
colour callbacks both screens hand render_path_graph — so the two graphs cannot
drift; pass source==self_name to draw both ends as us for a walk. A route that
revisits a node (a boomerang's mirrored return leg) collapses to distinct-in-
order before drawing, since the depth graph can only seat a node once; the route
line below still carries every hop. Move the shared _UNKNOWN marker down to
map_render alongside _SELF/_NODE/_REPEATER so widgets can reach it without a
cycle.
