feat:Migrate content & data pages and components to TypeScript; add types, update...

What does this MR do?

This merge request migrates key content and data pages, as well as their associated components, from JavaScript to TypeScript, adding type safety, improving UI layouts, and ensuring consistency with Tailwind CSS.

Pages updated:

• Projects.js → Projects.tsx
• LLMProjects.js → LLMProjects.tsx
• Roadmap.js → Roadmap.tsx
• News.js → News.tsx
• NewsDetail.js → NewsDetail.tsx

Components updated:

• RoadmapSection.js → RoadmapSection.tsx
• SummerCard.js → SummerCard.tsx
• BlockCard.js → BlockCard.tsx

---

Problem / Motivation

• Existing JS pages lacked type safety, increasing the chance of runtime errors.
• Some layouts and responsive designs were inconsistent.
• There was a need for modernized, maintainable code with improved readability and standardization.

---

Implementation Notes

• TypeScript Migration: Defined strict types for Project, News, and RoadmapItem. Added proper interfaces and props for components.
• UI / CSS Improvements: Refined spacing, responsive grids, and card layouts using Tailwind CSS.
• Linting & Formatting: Removed unused variables, fixed missing dependencies, and formatted code consistently.
• Backward Compatibility: No breaking changes; components maintain previous functionality.
