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.

+# UI revamp
+
+- the Synthesis panel (Integrate Phase, etc, LP, MP) contains global parameters -> Should go under the top "Params" button
+
+- 'Auto Spread All' should go under the 'Params' button too. It's a global action.
+
+- group 'Extract Partials' button with '+Partial' and 'x Clear All' ones.
+
+- add a sine / resonator toggle per partial to toggle between sine-based synth and resonator. 'Resonator (all)' takes precedence.
+
+- the partial's mini-spectrum should go under the right panel, since it's related
+
+- the partial's mini-spectrum should have a fixed dB range ([-40dB,10dB]?) instead of a dynamic one, to see the impact of amplitude modulation per partial
+
+- the messages' color is too dark, make them 80% gray when appropriate
+
+- streamline the CSS and styling, if possible
