⚡ Bolt: Optimize getSessionTotals usageRecords loop

💡 What:
Replaced three separate .reduce() calls on session.usageRecords with a single for loop in two dashboard session API routes.

🎯 Why:
To reduce multiple iterations over the usageRecords array into a single pass, lowering O(3N) overhead to O(N). This reduces the performance bottleneck of looping through multiple reduce iterations when parsing usage data in session data calculation.

📊 Impact:
Reduces array iterations for usage token totals from 3 to 1 per session.

🔬 Measurement:
The test suite in the web package has been run and validated that the functionality remains exactly the same while taking less execution time.

이 PR은 PR #14 (upstream PR vibemafiaclub#25)에 의해 대체되었습니다. PR #14는 이 PR의 getSessionTotals 최적화에 더해 세션 상세 API의 usageTimeline .map()까지 단일 루프로 통합하는 더 포괄적인 구현입니다. 닫겠습니다.
