Fix frontend API embed

[iameli]

Broken right now due to a Next.js upgrade. I may give up entirely on booting the production app and just embed the static version instead.

Hey there @iameli. A question popped in my mind now.

From what I see, you work with Livepeer team correct? If not, feel free to disconsider this question.

Would it be feasible to split the frontend startup from the API?
From what I could understand from exploring the code, it looks like the API only has the responsibility of starting the NextJS server when the args is required, so this decision could be moved up in the hierarchy and the decision could be made at the code that decides when to start the API.

This way we could have separated MAKE commands for frontend and API.
