Introduce a new Next.js `client` app for XRayPDF: adds frontend pages (dashboard, upload, layout, Navbar, globals) and API routes for documents (upload, OCR, pixel processing, delete, list). Include Tesseract traineddata (eng.traineddata), update next.config.ts to allow native server packages and remote images, update package.json to add dependencies (canvas, sharp, tesseract.js, pdfjs-dist, multer, uuid), and update Prisma schema. Also add .gitignore entries for user uploads/results and a README describing the project and architecture.
