Fix Missing /notebooks Route Handler (500 Error)

Task ID: ff1cf64e-13b3-463c-b6a2-63a4346cd6fc Layer: [Atlas] Priority: P95

Goal

Fix the 500 error on /notebooks route by creating the missing notebooks database table. The route handler exists in api.py and is fully implemented, but the underlying database table is missing, causing database query failures.

Acceptance Criteria

☑ notebooks table exists in PostgreSQL with proper schema

☑ /notebooks route returns 200 status code

☑ Page renders correctly (empty state or with notebook entries)

☑ All notebook-related routes work: /notebooks, /notebook/{id}, /api/notebooks

☑ Changes committed and pushed

Approach

Run the existing migration script add_notebooks_table.py to create the notebooks table

Verify the table was created successfully

Test the /notebooks route with curl

Verify the page renders correctly

Test related notebook routes

Started task: Fix missing /notebooks route causing 500 errors
Root cause identified: notebooks table doesn't exist in database
Found existing migration script at add_notebooks_table.py
Created notebooks table with proper schema (id, title, description, associated_analysis_id, associated_entities, file_path, rendered_html_path, timestamps)
Ran migration on both worktree and main database
Tested: curl http://localhost/notebooks → 200 ✓
Tested: curl http://localhost/api/notebooks → 200 ✓
Verified all key pages still load correctly
