Add Arabic RTL valuation-review prototype (React + Vite + Tailwind, PDF extraction)

[Moshbbab]

Motivation

• Provide an Arabic-first RTL prototype to speed up review of real-estate valuation reports with quick PDF text extraction, IVS/IFRS 13 checklist and risk flags.
• Enable lightweight export of a review summary to Word for handoff or record-keeping.

Description

• Add a new prototype at prototypes/valuation-review-app including index.html, package.json, package-lock.json, vite.config.ts, tsconfig.json, tailwind.config.js, postcss.config.js, and .gitignore to scaffold a Vite + React + TypeScript + Tailwind app.
• Implement the main UI in src/App.tsx which uses pdfjs-dist for PDF text extraction (extractPdfText), a keyword-based fakeExtractAssumptions extractor, an IVS/IFRS checklist, computed risk flags, and a Word export via onExportWord.
• Add app entry src/main.tsx and basic Tailwind styles in src/styles.css, and include a README at prototypes/valuation-review-app/README.md with run instructions (npm install / npm run dev).
• Configure PostCSS/Tailwind and Vite React plugin with TypeScript support and strict compiler settings in tsconfig.json.

Testing

• No automated tests were added or executed for this prototype.
