feat(mq_editor): UI revamp — params panel, layout, partial spectrum

- Move Synthesis controls (integratePhase, jitter, spread, resonator,
  LP/HP filters) and Auto Spread All into the ⚙ Params dropdown
- Group Extract Partials / +Partial / ✕ Clear All in one toolbar group
- Add per-partial Sine/Res mode toggle in the property panel (Mode row)
- Move partial mini-spectrum below the right panel (right-col layout)
- Partial mini-spectrum: dynamic dB range scanned across full duration
  (8 samples, [peak−60, peak]), cached on partial select
- Print bezier amplitude A= in red at top-right of partial spectrum
- Status/info messages set to 80% gray (#ccc)

handoff(Claude): UI revamp complete, TODO items implemented.
