feat: prioritize active developers in job matches by contribution activity

- Fetch 12 job matches and sort by heatmap total contributions in memory
- Show top 6 most active contributors to reduce empty heatmaps
- Handle missing heatmaps by treating total contributions as 0
- Enqueue heatmap sync for all 12 matches to improve future data
