Dashboard: public routes link to their public URL; drop editable behavior field

- Gateway route table: a public route's address now links to its public URL
  (green, with the tunnel icon) instead of the internal one.
- Program detail: remove the editable `behavior` selector — behavior is a derived
  label now and drives no logic, so editing it was meaningless (the stored value
  is preserved on save via the manifest spread).
