Updated Next Secure Download to Next.js 14 with App Router

I've just rolled out a minor update for my open source project, Next Secure Download, now fully embracing the power of Next.js 14! Here’s what’s new:

1. App Router Migration: I've moved from the classic Pages router to the more dynamic App Router, enhancing the project's flexibility and scalability.
2. Brand New Icon: Check out the sleek, new project icon! It's the fresh face of Next Secure Download.
3. Dedicated Sample Page: Experience the improvements first-hand on our sample page - now hosted on my personal domain: https://nextsecure.nico.fyi.
4. Enhanced Security: I've beefed up the security measures, especially when serving secret files. Peek at the updated code to see how it's safeguarding your file.
