Trezor Safe 3 not supported

Adding a Trezor Safe 3 does not work when selecting "Trezor" as device.

Steps to reproduce the behavior:
1. Go to 'Add Device'
2. Click on 'Trezor'
3. Click on 'Get via USB'
4. See error 'Internal error: unsupported trezor model'

- Windows desktop
- Specter Version [2.0.2]

Start with the Add Device flow and the USB path described in the reproduction steps, then trace the source of the “unsupported trezor model” error. Done means a Trezor Safe 3 can be selected as a Trezor device and added successfully through USB on Windows.
