(Chore) Plan and migrate server to vercel

[sirpy]

This epic is about the process required to migrate GoodServer from heroku to vercel

• Vercel works with serverless functions
• That would require to migrate our current API to next.js which vercel supports
• Currently we have some state(wallet)/cron jobs that are running on the goodserver and will have to be migrated or separated
• [ ] plan slow migration of API to vercel. ie we slowly move more and more endpoints to vercel, DAPP will send some requests to vercel and others to heroku, until we are done migrating.
• [ ] open issues for each task
