enhance(settings): Improve SecurityPostureSummary with score indicator

- Added dynamic security score calculation (0-100%)
- Added gradient header that changes color based on score:
  - Green (>=80%): Strong security
  - Amber (50-79%): Moderate security
  - Red (<50%): Weak security
- Improved visual hierarchy with color-coded status cards
- Added 'Critical' labels for important missing features
- Changed icons to lucide-solid for consistency
