Steam microphone update

Steam Streaming Microphone update for the Apollo mic passthrough fork.

Highlights:

• Windows host microphone passthrough now targets Steam Streaming Microphone instead of VB-CABLE
• redirected client microphone audio is rendered into Speakers (Steam Streaming Microphone)
• host applications should use Microphone (Steam Streaming Microphone) as the microphone source
• troubleshooting UI now includes a 5-stage microphone validation ladder
• recent microphone events are integrated into the main Troubleshooting log view
• web UI microphone descriptions were shortened and cleaned up for resubmission

Current requirement:

• use the matching Moonlight fork on the client side: https://github.com/logabell/moonlight-qt-mic
• stock Moonlight clients do not yet include the required microphone changes for this Apollo fork

Current host support:

• Windows: supported
• Linux: not supported yet for this microphone passthrough path
• macOS: not supported yet for this microphone passthrough path

Related repos:

• Apollo fork: https://github.com/logabell/Apollo
• Moonlight Qt fork: https://github.com/logabell/moonlight-qt-mic
• Moonlight common-c fork: https://github.com/logabell/moonlight-common-c-mic

Notes:

• this release reflects the current Steam Streaming Microphone implementation submitted upstream in ClassicOldSong#1428
• microphone passthrough requires encrypted microphone packets; plaintext mic transport is rejected for passthrough sessions
