What changed

Refreshed the Play Store dashboard and add-profile screenshots with more representative preview data:

• Dashboard cards now show the user-defined device label ("My AirPods Pro" / "AirPods Max") instead of "?".
• The dark dashboard showcases an AAP-connected device — full connectivity badge (BLE + IRK key + encrypted + AAP) and the ANC mode selector with "Adaptive" highlighted.
• The "Create Profile" preview is pre-filled with a profile name, model, and paired Bluetooth device, making the screenshot illustrate the complete setup flow.

Technical Context

• Added label to MockPodDataProvider's dashboard mocks. The popup screenshot was unaffected because it uses getLabel(context) which falls back to the model name; the dashboard card reads device.label directly with ? as the fallback.
• Refactored BluetoothDevice2 so address and name are primary constructor fields with internal: BluetoothDevice? optional. Previews can now mock it without a real Android BluetoothDevice. Adjusted the six callers that need the wrapped Android handle (AapAutoConnect x4 with !!, two reflection calls in BluetoothManager2 with explicit null bail-out).
• Bumped screenshot test maxHeapSize to 4g — the smoke batch (6 locales × 7 screens = 42 renders) was OOMing in layoutlib's image pool with the test executor's default heap.
• zh-CN re-rendered with mirrored (RTL) layout in this run; appears to be a layoutlib quirk specific to that locale, unrelated to this change. The mock data is correct; the layout direction needs a separate fix before the next full Play Store regeneration.
