Setup process: no user feedback if driver failed to pair with Roon

[zehnm]

If the driver cannot pair with Roon, there's no user feedback in the setup process. Only a timeout after a long time.

Console log shows a clear error that pairing failed:

[UC Integration API] [::ffff:192.168.1.234:62758] -> {"kind":"req","id":4,"msg":"set_driver_user_data","msg_data":{"confirm":true}}

[uc_roon] Failed to pair with Roon

Meanwhile the setup process is still running:

And finally times out:

[UC Integration API] [::ffff:192.168.1.234:62758] -> {"kind":"event","msg":"abort_driver_setup","cat":"DEVICE","ts":"2024-10-29T13:39:20.334245087Z","msg_data":{"error":"TIMEOUT"}}

Expected:

• Error message sent back to the core if pairing failed.
