Add MAC vendor update script and vendor-to-device-type mapping

Introduces backend/data/update_mac_vendors, an executable Python 3 script
that downloads the latest MAC vendor database from maclookup.app and
generates vendor-device-type.json — a mapping of vendor names to device
types (phone, laptop, tablet, server, tv, printer, network_appliance,
home_security, home_appliance, watch, pc, gaming_console) used for
auto-assigning device type on first detection.

+update_mac_vendors
+
+Downloads the latest MAC vendor database from maclookup.app and regenerates
+the vendor-to-device-type mapping used by the backend for auto device classification.
+
+Outputs (relative to the script's own directory):
+  mac-vendors-export.json   - raw vendor database (replaces existing)
+  vendor-device-type.json   - vendor name -> device type mapping (non-unknown only)
