fix: Read WiFi/BT data from v2 scanners in analytics dashboard

The analytics summary, health, and export were only reading from legacy
DataStores (app_module.wifi_networks, bt_devices) which the v2 WiFi and
Bluetooth scanners don't populate. Now checks v2 scanner singletons
first and falls back to legacy stores.
