Implemented caching for the DBus DeviceProxy to optimize repeated calls to list_enrolled_fingers. This avoids recreating the proxy (and potentially re-introspecting) every time the list of fingers is refreshed.

Key changes:

  • Added device_proxy field to AppModel.
  • Modified find_device to return the constructed proxy.
  • Updated DeviceFound message to transport the proxy.
  • Updated list_fingers_task to use the cached proxy.

Avoid creating a new DeviceProxy for every `list_enrolled_fingers` call.
Instead, create it once when the device is found and store it in `AppModel`.
This reduces allocation overhead and potential DBus introspection traffic.

Changes:
- `AppModel` now stores `Option<DeviceProxy<'static>>`.
- `find_device` returns both the object path and the proxy.
- `list_enrolled_fingers_dbus` accepts a reference to an existing proxy.
- `Message::DeviceFound` carries the proxy along with the path.
