Add names to "Current audio devices:" list

[MustBeArt]

Currently we see something like this when Interlocutor starts up:

📱 Current audio devices:
   Input:  1
   Output: 2
Do you want to change these? (y/N): y

There are two problems with this. Mainly, the human user can't really be expected to memorize the mapping between numbers and actual audio devices on their system. But also, that mapping can change often, with the connection or disconnection of a USB headset, for instance.

It would really be better to see something like the select menu already has:

🎤 Select Input Device:
   1. iPhone 17 Prorange Microphone [Core Audio] (1 in)
   2. Logi USB Headset [Core Audio] (1 in)
   3. MacBook Air Microphone [Core Audio] (1 in)
   4. Camo Microphone [Core Audio] (2 in, 2 out)
   5. RØDE Connect System [Core Audio] (2 in, 2 out)
   6. RØDE Connect Virtual [Core Audio] (2 in, 2 out)
   7. RØDE Connect Stream [Core Audio] (2 in)

Choose input device to test (1-7): 2
