luci-proto-wireguard: fixed bug with incorrect peer name detection

Fixed bug with incorrect peer name detection on `Status -> WireGuard`
page when more than one peer with the same public key exist:
1. Peers are now tested not only by public key, but also by
enabled/disabled status, peer host (both IP and FQDN are supported)
and port.
2. Added required `resolveip` dependency.

Closes #7342
