Clean up frontend file structure and link navigation components to pages

[tjhiaj]

File Structure Cleanup

• Components are grouped logically (e.g., components/, pages/, layouts/)
• Shared components (Navbar, Footer) live in a common directory
• Page-specific components are separated from reusable components
• Unused files, dead code, and commented-out blocks are removed
• Folder and file naming conventions are consistent
• No build artifacts or generated files are committed

Navbar links route to the correct pages:

• Home
• About Us
• Events
• Contact

Footer quick links route to the same canonical pages as navbar
