Changes:
- Migrate validation preview from http://glenlis/spooler_db/main_dev.php to CI4 /report/{accessnumber}
- Add ReportController::preview() for HTML preview in validation dialog
- Add ReportController::generatePdf() to queue PDF generation via node_spooler at http://glenlis:3030
- Add ReportController::checkPdfStatus() to poll spooler job status
- Add ReportController::postToSpooler() helper for curl requests to spooler API
- Add routes: GET /report/(:num)/preview, GET /report/(:num)/pdf, GET /report/status/(:any)
- Delete public/spooler_db/ directory (40+ legacy files)
- Compact node_spooler/README.md from 577 to 342 lines
Technical Details:
