chore(screenshots): Improve dashboard and add-profile previews

Use AAP-connected mocks for the dark dashboard to showcase full connectivity badges (BLE + IRK + encrypted + AAP) and the ANC mode selector. Populate the add-profile preview with a demo name, model, and paired device. Add user-facing labels to the dashboard mock devices.

Refactor BluetoothDevice2 so name/address are primary constructor fields, letting previews construct one without a real Android BluetoothDevice. Bump the screenshot test JVM heap to 4g — the smoke batch (42 renders) was hitting the test executor's default ceiling.
