Extract the canvas frequency-response math, the custom vertical fader, the
AutoEQ parser, and the AutoEQ search panel out of Equalizer.tsx:
- utils/eqCurve.ts biquadPeakResponse + drawCurve
- utils/autoEqParse.ts AutoEq types + parseFixedBandEqString
- components/equalizer/VerticalFader.tsx
- hooks/useAutoEq.ts AutoEQ search/apply state
- components/equalizer/AutoEqSection.tsx
Pure code-move, no behaviour change. Both call sites (AudioTab, PlayerBar)
default-import Equalizer unchanged.
