Block BitTorrent on the server

- awg-ctrl: optional nft table awg_torrent (GET/PUT /api/torrent, off by
  default). A connection is judged by its first packets, like Xray's
  sniffing: DHT, UDP trackers, uTP SYN, and with @ih support the plain
  TCP handshake and HTTP announce. A match marks the connection in
  conntrack and drops it whole; without @ih only the UDP part is used
- devices that tried are kept in a 10-minute set and flagged as
  "torrent" in user and device stats; with shaping on they sit in the
  background class while the flag lasts
- metrics: awg_torrent_block_enabled/active, awg_torrent_blocked_total,
  awg_torrent_devices and per-peer awg_peer_torrent
- panel: "Торренты" section in server settings, "торренты" chip on users
  and devices; Save sends only what changed
