fanyang 57cc9922a4 hotpath: add measure to MpscTunnelSender::send and send_msg_by_ip ...

Adds hotpath::measure to two critical blind spots in the send chain:

1. MpscTunnelSender::send — the tokio mpsc channel send point, which
   accounts for 84% of PeerConn::send_msg wall time (2.33us/pkt).

2. PeerManager::send_msg_by_ip — the top-level packet send entry point,
   revealing a 1.04us gap between send_msg_by_ip and send_msg_internal
   (encryption + routing + ACL + fan-out).

Full send chain timing now visible:
  send_msg_by_ip:       3.83us
    └─ send_msg_internal: 2.79us  (gap: 1.04us = encrypt + route + ACL)
        └─ MpscTunnelSender::send: 2.33us  (84% of internal)
