- Fix off-by-one bug in wg_dump(): handshake was read from parts[5] (rx_bytes),
now correctly reads from parts[4]; rx/tx shifted accordingly
- Run wg show via sudo to work under unprivileged wgadmin user
- Remove NoNewPrivileges from systemd service (needed for sudo)
- Merge Handshake column into Status badge (shows "online · 2м назад")
- Add humanize_ago() for human-readable handshake time
- Add next_free_ip() to suggest next available IP in new peer form
- Add device type quick-select buttons (Phone/Laptop/PC/Router/Server/Tablet)
- Placeholder in AllowedIPs now shows the real next free IP
- Traffic column shows ↓ rx / ↑ tx separately
