Add inline controls, custom icon, gold color scheme, and tuned voice detection

- Move font size, scroll speed, and mic sensitivity sliders into the
  main window for quick access
- Replace generated icon with vintage microphone SVG
- Update color scheme to match icon palette (gold/bronze accent)
- Add loading spinner on Start button until teleprompter panel appears
- Boost audio power curve (0.4 -> 0.3) for better voice pickup
- Tune scroll stop responsiveness: faster hold, decay, and easing
- Raise default mic sensitivity threshold to reduce false triggers
- Update default welcome text to reference inline controls
