feat: initialize k-tv-frontend with Next.js and Tailwind CSS

- Added package.json with dependencies and scripts for development, build, and linting.
- Created postcss.config.mjs for Tailwind CSS integration.
- Added SVG assets for UI components including file, globe, next, vercel, and window icons.
- Configured TypeScript with tsconfig.json for strict type checking and module resolution.
