feat(prospecting): show per-category score breakdown on prospect detail

- Restructure score_breakdown from flat dict to grouped by category:
  {technical_health: {flag: pts}, modernity: {...}, ...}
- Each category row shows score/max with progress bar + per-flag detail
  (e.g. Technical Health 15/40 → "very slow: 15 pts")
- Color-coded: green for positive flags, orange for issues
- "No issues detected" shown for clean categories
