Add traffic-based prioritization to batch analyzer

- Sort domains by priority: high-traffic optimization > low-traffic optimization > optimized
- Display traffic indicators: CRITICAL (20+), HIGH (10+), MEDIUM (5+), LOW (<5)
- Helps users focus on domains that matter most (high-traffic + need optimization)
- Uses color coding to make traffic levels visually obvious
- Includes peak concurrent request count in traffic indicator
- Makes it easy to identify which domains to optimize first
