⚡ Bolt: Optimize Prisma relation iteration over usage records

[seonghobae]

💡 What

Replaced multiple chained .reduce() calls that were iterating over the same session.usageRecords array with a single for...of loop in two dashboard session endpoints:

• packages/web/src/app/api/orgs/[orgSlug]/dashboard/sessions/route.ts
• packages/web/src/app/api/orgs/[orgSlug]/dashboard/sessions/[sessionId]/route.ts

🎯 Why

When dealing with large datasets returned from Prisma include blocks, iterating over the same relation data multiple times in memory (via chained .reduce or .map calls) introduces unnecessary CPU overhead and can lead to performance bottlenecks under load.

📊 Impact

• Reduces array iteration passes from $O(3N)$ to $O(N)$ for usageRecords aggregation.
• Lowers memory pressure and CPU cycles during data serialization.
• Improves overall response time for dashboard session APIs, especially for sessions with many usage records.

🔬 Measurement

1. Run the web test suite to ensure no regressions in cost calculation logic:

   cd packages/web && pnpm test

2. Benchmark the API response times for organizations with a high volume of usageRecords in their sessions to observe the performance improvement.
