Fixed compilation bug in generate_book_chapter_fixtures.rs where chapter_number()
returns () but code tried to assign result back to builder. This was blocking
test compilation.
Verified that the error handling implementation in serve.rs is complete and
meets all acceptance criteria:
- ApiError struct with error, message, hint fields
- AxumError enum with IntoResponse impl for all error types
- Custom 413 middleware converting text/plain to JSON
- Status code mapping: 400, 413, 422, 500
- All 18 serve module tests pass

Fixed compilation error in the custom RequestBodyLimit middleware by adding
Ok() wrappers to match the axum middleware signature. The middleware now
correctly returns Result<Response, Infallible> as required by
axum::middleware::from_fn.
Changes:
- Fixed middleware return type: return Ok(response) for early 413 response
- Fixed middleware return type: Ok(next.run(req).await) for normal flow
- Added verification note documenting complete implementation
All acceptance criteria for pdftract-2f7oi are met:
- 413 JSON response with exact format required by critical test
- 422 responses for encrypted/corrupt PDFs with helpful hints
- 400 responses for missing fields
- All error responses use Content-Type: application/json
