feat(scanner): enrich device identification and vendor lookup

[usamaiqb]

Bundle the full IEEE OUI database and resolve vendors from it, fall back to the AP BSSID for the router MAC (ignoring Android's redacted value), populate vendor from SSDP manufacturer, add ARP-only devices that don't answer ping, and resolve hostnames via the gateway's own DNS server.

Closes #56
