Changed spectrogram to use transparency for low values
instead of interpolating from background color:
- Low signal values (0-64) fade from transparent to blue
- Background color shows through transparent areas
- Now matches FrequencyAnalyzer theme behavior
- Both analyzers use bg-muted/30 wrapper for consistent theming

Track levels were being converted to dB scale twice:
1. First in useMultiTrackPlayer via linearToDbScale()
2. Again in TrackFader via linearToDb()
This caused tracks to show incorrect meter levels compared to master.
Now both track and master levels store raw linear values (0-1) and
let the fader components handle the single dB conversion for display.

Previously, master meters received raw linear values (0-1) while track
meters received dB-normalized values, causing inconsistent metering display.
Now both master peak and RMS levels are converted using linearToDbScale()
for accurate comparison between track and master levels.
