feat: add PDF to Word conversion tool

[Srivarshan-T]

• Updated package.json to include new dependencies: docx and html-docx-js.
• Added localization support for the new PDF to Word feature in multiple languages (de, en, es, fr, hi, ja, nl, pt, ru, zh).
• Implemented the PDF to Word conversion functionality in a new component.
• Created service logic to handle PDF processing and conversion to Word format.
• Added tests for the PDF to Word conversion service to ensure functionality and accuracy.

This PR implements client-side PDF to Word conversion using pdfjs-dist for PDF parsing and docx for Word generation.

✅ Key Enhancements:

• Preserves line height, spacing, and structure
• More accurate layout for resume-style PDFs
• Optimized for multi-page documents

🆚 Note:
A similar PR (#205 ) was opened earlier by another contributor. This PR builds upon that idea but takes a different approach with additional improvements and cleaner formatting. Happy to collaborate or refactor based on reviewer feedback.

Fixes: [#69]

This is not easy. Better to use a library

[Srivarshan-T]

ok I will improve the accuracy especially with layouts and images

After spending several hours researching this, I found that accurate PDF to Word conversion is not feasible using frontend-only solutions. It typically requires either a strong backend setup (e.g., Python scripts or Node.js processing) or third-party APIs — most of which are either limited in functionality or require paid plans for reliable results.

Since implementing this purely in-browser isn't practical without significant compromises, I’m moving forward to work on another issue. Open to suggestions if we plan to support a backend for this feature in the future!
