Question Paper Export as Printable PDF

[ankit2101]

Summary

Let admin export the AI-generated question set for any chapter as a formatted, printable PDF with the CBSE three-section layout (Section A / B / C), mark allocations, and question numbering.

Why

Teachers use digital question banks to generate offline test papers. This makes the AI question generation valuable beyond the digital test — it doubles as a lesson planning and paper-setting tool.

Implementation Notes

• Backend: use reportlab or weasyprint to render the cached question JSON to PDF
• New endpoint: GET /api/admin/chapter/<id>/question-paper
• Frontend: 'Download Question Paper' button in the Content tab per chapter (only if questions are cached)
• Include: school name placeholder, chapter name, board, grade, subject, date, three sections

Acceptance Criteria

• 'Download Question Paper' button appears for chapters with cached questions
• PDF is formatted with Section A / B / C layout
• Mark values shown per question
• Answer key is a separate page at the end (key points listed)
