feat: Implement rating prompt feature across tools

- Added a rating prompt dispatch mechanism to various tools (ChatPdf, PdfFlowchart, QrCodeGenerator, SummarizePdf, TranslatePdf, TableExtractor) to encourage user feedback after tool usage.
- Introduced a new utility for handling rating prompts, including event dispatching and current tool identification.
- Updated the ToolRating component to manage user feedback submission, including UI enhancements and state management.
- Enhanced the sitemap generation script to include new routes for pricing and blog pages.
- Removed hardcoded API key in pdf_ai_service.py for improved security.
- Added a project status report documenting current implementation against the roadmap.
- Updated translations for rating prompts in Arabic, English, and French.
- Ensured consistency in frontend route registry and backend task processing.
