Modern devices increasingly use randomized ("Private WiFi Address") MACs,
which are locally administered and have no real OUI, so the MAC-prefix
vendor lookup returns nothing. Such devices still advertise distinctive
mDNS service types, which we now use to deduce their vendor.
- Extend the mDNS parser to also capture PTR service types alongside
A-record hostnames.
- Add a service-type -> vendor mapping (data/mdns-service-vendor.json) and
a service_vendor_finder, using canonical vendor names so device-type
resolution still chains.
- Add utils::network::is_locally_administered to detect randomized MACs.
- In the mDNS scanner, fall back to service-based deduction only when the
OUI lookup is empty and the MAC is locally administered.
- Group the three finders under a new data module.
- Preserve a known vendor (and its derived device_type) when a later
sighting cannot deduce one, and suppress the spurious "vendor changed"
notification in that case.
