fix(ui): folds tokens for ML-denoise panel + screenshare popover (native-cinny audit 3/N)

- General ML noise-suppression panel: ungated --border-color/--bg-card/--bg-input/
  --accent-orange -> color.Surface.ContainerLine/Container, SurfaceVariant.Container,
  Primary.Main. (The lotusTerminal-gated Boot button keeps its TDS --accent-orange.)
- CallControls "Share your screen?" popover: --bg-surface/--bg-surface-border ->
  color.Surface.Container / ContainerLine.
