feat: Update index.html and add media files for photo wall project
- Modified index.html to include favicon, title, and linked assets for Vite app. - Added three new media files: LaguBangsaJohor.mp4, LaguNegaraku.mp4, and LaguTeoChew.mp4. - Created nameList.json containing the names of the first founders with their status. - Introduced demo/photoWall/v0/index.html for a dynamic carousel with background video and marquee text. - Added demo/photoWall/v1/index.html for a photo wall layout with responsive design. - Created demo/photoWall/v3/images.json and nameList.json for image and name data. - Implemented demo/photoWall/v3/index.html with Vue.js for an interactive photo wall experience.
