Fix neighbours command: show details via remote CLI, add name and CB state

The neighbours output was gated by !ctx.buf so details were only
visible on local Serial. Removed the guard and added buffer overflow
check like the nodes command. Output now shows resolved node name
and circuit breaker state instead of raw 6-byte pubkey prefix.
