fix(bonfire): reroute only the owning console's lines to a live view

- the registered view keeps the console that started it; Println, Printf
  and status lines go above it only from that console, other consoles
  write to their own writers (bonfire.PrintAbove still reaches any view)
- runLive claims the single live slot by check and set under liveMu and
  reports when it could not, so the widget prints plain lines
- unregister, finish and wait run deferred, so a panic in work leaves no
  registration behind and still propagates (WR-02)
