fix(recording): Fix phone call audio capture with amix filter
Phone calls were not capturing the remote person's voice due to severe
volume loss (44 dB) when using the amerge+pan FFmpeg filter combination.
Changes:
- Replace amerge+pan with amix filter (provides 44 dB volume improvement)
- Increase default system volume from 0.5 to 2.0 for better capture levels
- Add diagnostic tool to show active audio playback (C-; r w)
- Add integration test with real voice recording
- Fix batch mode compatibility for test execution
The amix filter properly mixes microphone and system monitor inputs without
the massive volume loss that amerge+pan caused. Verified with automated
integration test showing perfect transcription of test audio.
