Show mic source in main UI

[iu2frl]

Main UI now allows changing the audio input by looping trough all available mic sources (useful for devices with multiple inputs like the IC7300MK2 or the IC7610)

What happens if you don't select the mic (the way it is now)? Does the application work?

[iu2frl]

Yes, the application works but the radio is keyed with no audio being transmitted (tested on 7300 MK2)

Thanks for the contribution! However, wfweb already handles mic input selection automatically — and we've just improved it to also cover LAN-connected rigs like the IC-7300 MK2.

When enableMic is called, the backend detects how the rig is connected (USB or LAN) and automatically sets DATA MOD OFF to the correct input. When the mic is disabled, the original setting is restored. There's nothing the user needs to select manually.

The fix is on branch fix-auto-mic-input — could you test it with your IC-7300 MK2 over LAN and confirm it works? If it does, we'll merge that and close this PR.

The current input selection did not work for me and it was forcing it to USB. I will try the new branch and keep you posted
