Remove dev server so client can be static built, replace with proxy

[lalalune]

Describe the bug Right now we are running a dev server which will is fine but will not work on Vercel. We could definitely come up with a better solution, as @soulofmischief has suggested.

If we run the client directly with vite instead of running the dev-server.mjs, we have CORS errors with the compiler. To reproduce this issue, switch the "dev" command in the client package to call vite instead of node dev-server.mjs

• Remove need for dev-server.mjs in client
• Fix CORS handling between client and compiler so it just works, maybe adding a proxy to the client
• Set up so client just works as a static build and publishes correctly to vercel.
• Deliverable is the client and compiler published to vercel and working with each other correctly
