Display signal quality score on analytics dashboard

- Add signalQualityScore to LastTrade interface
- Display quality score badge in last trade section (0-100)
- Color-coded: green (80+), yellow (70-79), orange (60-69)
- Shows 'Excellent', 'Good', or 'Marginal' label
- Gracefully handles null values (old trades without scores)
- Better layout when quality score is present
