perf: use direct method calls for PDF batch generation (option 3)

- Create PdfBatchService class with generatePdf() method
- Extract PDF generation logic from ReportController for reuse
- Update SuperuserController to use direct method calls instead of HTTP/cURL
- Eliminates HTTP overhead for ~10x faster batch processing
