Sebastian Krüger 8367cbf6e7 fix: switch from RMS to peak detection for more accurate level meters ...

Changed level calculation from RMS to peak detection to show
more realistic and responsive meter values.

The Problem:
- RMS calculation produced values typically in 0-30% range
- Audio signals have low average RMS (0.1-0.3 for music)
- Meters appeared broken, never reaching higher levels

The Solution:
- Switched to peak detection (max absolute value)
- Peaks now properly show 0-100% range
- More responsive to transients and dynamics
- Matches typical DAW meter behavior

Algorithm Change:
Before (RMS):
  rms = sqrt(sum(normalized²) / length)

After (Peak):
  peak = max(abs(normalized))

Applied to Both:
- Recording input level monitoring (useRecording)
- Playback output level monitoring (useMultiTrackPlayer)

Benefits:
✅ Full 0-100% range utilization
✅ More responsive visual feedback
✅ Accurate representation of audio peaks
✅ Consistent with professional audio software
