v0.85.0 — proxy pairing fix

Fixed

• Proxy-mode pairing failed when the host also has a local BlueZ adapter (forum post #4). The config flow now asks the HA Bluetooth registry which scanner actually sees the device and skips D-Bus pairing when it is a remote (ESPHome proxy) scanner — bonding is handled by the proxy on connect. Previously pairing died with InterfaceNotFoundError: org.bluez.Device1 because it introspected a device object the local hci0 adapter had never seen.

Thanks @Spitfyre for the detailed report with the stack trace.
