TASK 8 meter scaling: +10 dB input amplification in AudioLevelMeter.ToDisplay so the meters use the full bar — speech peaks (~0.2 RMS, -14 dBFS) read ~0.93 (red zone) and normal speech (~0.05, -26 dBFS) ~0.73 (yellow) at maxed volume, instead of hovering at the red edge; ≤0.001 linear still reads zero so the meter never idles on background noise; one knob shared by the mic bar and the game bar (× MicVolume gain-on-noise untouched); tests updated + new ToDisplay_Pushes_Speech_Peaks_Into_Red_At_Maxed_Volume — 171 tests passing, 0 warnings
