fix: enrich peer dashboard and services API endpoints

/api/peer/dashboard now returns live WireGuard stats (online, rx_bytes,
tx_bytes, last_handshake, allowed_ips) by calling wireguard_manager.
/api/peer/services now returns a structured dict with wireguard, email,
caldav, webdav sections containing hostnames and credentials.
Fixes 2 failing E2E API tests.
