fix(mq_editor): partial mini-spectrum — correct FFT, time selection, resonator sync

- Fix: fftRadix2 called without bitReversePermute → noisy spectrum (use fftForward)
- specTime = mouse pos if inside partial [t0,t3], else center of partial interval
- Cache check moved before canvas clear to keep spectrum visible outside [t0,t3]
- viewer.synthOpts forwarded to synthesizeMQ so forceResonator/globalR/gain apply
- invalidatePartialSpectrum() wired to forceResonator/forceRGain/globalR/globalGain

handoff(Gemini): mini-spectrum now correct; fft bug fixed, resonator mode synced
