Implement three-layer button architecture for consistent formatting button styling

Browse Source 
- Add button frame isolation layer to prevent site CSS from affecting toolbar appearance
- Create style sample container for authentic style previews without layout interference
- Update CSS with proper containment boundaries and !important rules for button structure
- Preserve all authentic styling (color, weight, transform, decoration) in isolated preview
- Fix inconsistent button appearance across different site stylesheets (e.g. .brand class)
- Maintain professional toolbar UX while showing accurate style previews
