What changed

When the ANC widget can't reach your AirPods, it now shows the device profile name and whether the pods are nearby or out of range, instead of a bare "Not connected".

Technical Context

• The !isAapConnected branch in AncWidgetRenderStateMapper now sets Message.primaryText to the profile label (falling back to device.getLabel(context)) and Message.secondaryText to one of two new descriptions, picked by device.ble != null.
• WidgetDeviceKey gained a hasBleAdvertisement field. Without it, the distinctUntilChangedBy filter on widgetDeviceFlow would swallow the nearby ↔ not-nearby transition (isAapConnected stays false either way), and the widget would stay stuck on the previous message until something else in the key changed.
• Scope is ANC widget only. Battery widget gets battery data from BLE, so it never lands in this state. Mixing battery info into the disconnected ANC widget was rejected as inconsistent — the active widget has no battery line.
• anc_widget_aap_not_connected_label ("Not connected") is intentionally kept because AncTileService reuses it for the Quick Settings tile.
