fix(ui): folds tokens for settings/profile/glass invented vars (native-cinny audit 2/N)

- DenoiseTester: --bg-card/--border-color/--accent-green/--accent-orange -> color.Surface.*/Success/Primary
- ProfileDecoration: --accent-cyan/--bg-surface-variant -> color.Primary.Main/SurfaceVariant.Container
- Profile: --tc-critical/warning-normal -> color.Critical/Warning.Main
- UserRoomProfile: --tc-positive/warning-normal/--tc-surface-low-contrast/--bg-surface-variant -> color tokens
- Sidebar glass: hardcoded rgba bg/border -> color-mix on color.Surface.Container + SurfaceVariant.ContainerLine
  (also fixes the glass looking wrong on light themes — was always near-black)
