Clarify STT Mic Mute

[taliyahwebb]

Why

STT microphone mute does not mute the microphone but instead just suppresses STT output.

What

Either

• Fix the UI to reflect that
• Change functionality to actually mute input
• (??) remove this element as users can mute their input device directly?

I don't know if we can change it to an actual mute
For WSA and Browser we don't have control over the input
Not sure if it's possible for Azure
For Deepgram i would assume we can just temp stop the requests by adding a condition here https://github.com/taliyahwebb/curses/blob/master/src%2Fserver%2Fservices%2Fstt%2Fservices%2Fdeepgram.ts#L40 (not actually mute but doesn't send so it's ok i guess)

For me the best solution would be to implement the actual mute for the services we can, and fall back on a clearer version of the current system if we can't
Note that if we have for example Whisper active with a correct mute, we would probably need to keep the current behavior as well because Browser can be running in the background
