Fixed several TypeScript issues:
- Changed 'formatter' to 'formatValue' in CircularKnob props
- Added explicit type annotations for formatValue functions
- Initialized animationFrameRef with undefined value
- Removed unused Waveform import from TrackControls
All type checks now pass.

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

Updated both FrequencyAnalyzer and Spectrogram to use
light gray background (bg-muted/30) that adapts to the theme:
- Wrapped canvas in bg-muted/30 container
- FrequencyAnalyzer reads parent background color for canvas fill
- Spectrogram interpolates from background color to blue for low values
- Both analyzers now work properly in light and dark themes

Added real-time audio analysis visualizations to master column:
- FrequencyAnalyzer component with FFT bar display
- Canvas-based rendering with requestAnimationFrame
- Color gradient from cyan to green based on frequency
- Frequency axis labels (20Hz, 1kHz, 20kHz)
- Spectrogram component with time-frequency waterfall display
- Scrolling visualization with ImageData pixel manipulation
- Color mapping: black → blue → cyan → green → yellow → red
- Vertical frequency axis with labels
- Master column redesign
- Fixed width layout (280px)
- Toggle buttons to switch between FFT and Spectrum views
- Integrated above master controls with 300px minimum height
- Exposed masterAnalyser from useMultiTrackPlayer hook
- Analyser node now accessible to visualization components
