[Nebula] Feature: Farcaster Mini App

[PaoloRollo]

This PR allows the Nebula website to become a Farcaster Mini App.

Some important changes

• I've changed in the next.config.ts file the security header X-Frame-Options to allow as frame-ancestors only self and farcaster.xyz to allow the Mini App to be opened from browser, since the browser version of Farcaster opens the apps using iframes
• I've moved all the .well-known files of the dashboard under NextJS API routes in order to dynamically generate a farcaster.json based on the environment file

There are 4 new environment variables that need to be added:

NEXT_PUBLIC_APP_URL= # this is the app url, for prod is https://nebula.thirdweb.com
NEXT_PUBLIC_FARCASTER_HEADER= # farcaster manifest account association header generated on farcaster.xyz
NEXT_PUBLIC_FARCASTER_PAYLOAD= # farcaster manifest account association payload generated on farcaster.xyz
NEXT_PUBLIC_FARCASTER_SIGNATURE = # farcaster manifest account association signature generated on farcaster.xyz

How to test it

In order to test the Mini App, you need to have ngrok installed and you need to point it at http://nebula---localhost:3000 (ngrok won't work on local subdomains). Then, you need to set the NEXT_PUBLIC_APP_URL variable to your ngrok url, open the Mini App on Farcaster DevTools and generate the account association header, payload and signature. Get those values, and populate the missing env variables.

When this is all done, you can test your mini app both on browser and on your phone.
