feat(desktop): read gamepad battery from power_supply
BluetoothRow only read BluetoothDevice.battery, which is BlueZ's
org.bluez.Battery1. A gamepad never publishes that interface: a Sony pad
exposes its charge as a kernel power_supply instead, so the percentage never
appeared.
Read every power_supply whose name ends in a MAC on a 30s timer while
anything is connected, keyed by address. BlueZ still wins when it has a
value.
