Code Refactored and modularized

[N3XT14]

This PR introduces significant refactoring and modularization to enhance code organization and maintainability. Key changes include:

Modularization of CLI Logic:

• Extracted command handling logic into a dedicated utility file (cliUtils.ts) along with types, etc in their respective folder.

API Call Integration:

• Added a layout for making REST API calls based on commands entered in the CLI.
• This layout serves as a mock implementation to simulate interactions with the backend.

Thanks to @rishavvajpayee a good portion of UI was already created considering what the objective of the PR was. For integrating with API. I am not completely sure about the URL and format if that's ready but I have created the wrapper which should make the later work easy and quick.

Let me know if something else needs to be done.

I have integrated the CLI API.
Once Backend is up all we need to do is change the constant file apiEndpoints.ts

There were 2 issues I observed which I am describing here regarding playground-mono.

1. Handling of CORS
2. Handling of headers such as setting content-type: applicaton/json. I believe we should check on server side about this or else we should throw errors when headers are set from frontend

Would it be better if this derived via config/env var?

[N3XT14]

Yes. In fact NextJS has built-in support for that, So we can have .env, .env.development, and so on to handle them.
