Ken Sanislo dbd054c468 Add debug logging around Centurion device_addr probe
Temporary diagnostics for field-testing the probe fix. Each step of
the probe loop logs attempt number, bytes received, and the first 4
bytes of the RX frame so a `solaar -dd` trace shows exactly what the
device returned (or didn't).

Also adds a WARNING log in Device.battery() when it falls through to
the HID++ 1.0 path on a Centurion device. If that warning ever fires
in the wild, it means the probe silently failed and the next step will
be the register read that returns INVALID_SUB_ID_COMMAND — a direct
breadcrumb from cause to crash.

Revert this commit once we've confirmed the probe works reliably on
reporter hardware.

Solaar

Solaar is a Linux manager for many Logitech keyboards, mice, and other devices that connect wirelessly to a Unifying, Bolt, Lightspeed or Nano receiver as well as many Logitech devices that connect via a USB cable or Bluetooth. Solaar is not a device driver and responds only to special messages from devices that are otherwise ignored by the Linux input system.
