⚡ Bolt: Remove redundant API query for project lists

[aicoder2009]

💡 What:

Removed the duplicate API fetch call to /api/projects/[id]/lists in src/app/projects/[id]/page.tsx when fetching project details. The component now derives the project's lists in-memory by filtering the globally fetched allLists (/api/lists) collection.

🎯 Why:

The frontend was fetching both a global collection of lists (/api/lists) and a strict subset of that collection (/api/projects/[id]/lists) concurrently. This created a redundant database query on the backend. Because we already had all the user's lists available in memory, it is significantly more efficient to simply filter that array by projectId instead of burdening the database and network with an extra request.

📊 Impact:

• Eliminates 1 HTTP request per project detail page load.
• Eliminates 1 DynamoDB query operation per project detail page load.
• Marginally reduces frontend CPU overhead by eliminating an extra JSON parsing step.

🔬 Measurement:

1. Navigate to a project detail page (e.g., /projects/[id]).
2. Observe the Network tab in the browser DevTools. Only two data fetch requests should be visible (/api/projects/[id] and /api/lists), and the /api/projects/[id]/lists request will no longer occur.
3. Verify the lists still render correctly in the project detail view.

📝 Walkthrough

Walkthrough

The change modifies ProjectDetailPage to fetch the project and global lists collection concurrently, removing a separate call to a project-specific lists endpoint. Project-scoped lists are now derived by filtering the global lists in-memory by projectId. A documentation note describes this redundant-query pattern.
