netcfg: enhance TCP socket listing with queue sizes

Browse Source 
TCP sockets in /scheme/netcfg/sockets/list now display:
  tcp: Established 10.0.0.1:80 -> 10.0.0.2:1234 sendq=0/128 recvq=0/128

Fields added:
- sendq: bytes queued for transmission (send_queue / send_capacity)
- recvq: bytes waiting in receive buffer (recv_queue / recv_capacity)

Mirrors Linux 'ss -tm' output showing send-Q and recv-Q.

All 31 tests pass.
