VPN connection log: who connected and when

WireGuard has no connect events, only the last handshake and byte counters. awg-ctrl now checks them every 30 s and writes conn_log in users.db: connect at the first handshake, disconnect at the last activity (the last tick the counters moved), with the session length and traffic, plus peer_seen, the last time each peer was online. Open sessions are restored from the database, so a restart adds no duplicates; a down interface is not a disconnect; a peer removed mid-session is closed. Events keep the name, owner and VPN IP as of that moment and live 90 days. Client public IPs are not recorded. GET /api/connlog serves the events and the per-peer last-seen list. The panel fetches it from the selected server at /ui/connlog and fills in master key labels and device names for sen:// peers. A new "Подключения" tab shows the event feed with search and paging, and "who was online when", including those who never connected.
