fix(ui): NATIVE-CINNY LAW — replace emoji with folds icons in settings

- Notification profile presets (P5-27) used literal emoji (🎮/💼/🌙) instead of
  folds Icons → Gaming=Ball, Work=Monitor, Sleep=BellMute.
- Permissions "Powers" list used ✅/❌ text emoji for has/no-power → folds
  Icons.Check / Icons.Cross (colored via the row).

Reviewed the rest of the UI: seasonal-theme picker emoji kept (folds has no
holiday-icon equivalents; a distinctly-Lotus visual feature), soundboard clip
emoji kept (user-chosen clip identity), URL-preview brand glyphs + upstream
device-verification emoji + keyboard key-symbols left as-is.

(Also records the F2 URL-preview decision: keep default-on.)
