Chore belindas nextjs update api evironment

[IsaacJrTypes]

This PR contains a quality of life update! Now you can set the API address from your .env file. If the developer is using a localhost based API address, the API address will be printed to the console.

How to test:

• Use the .env.sample to help set up your .env file. Once set, use npm run dev and run backend
• Make sure localhost port number matches with backend port number

Great job. We would need to document this as well.

Changing the api address via the env seems to be working. I can set it to anything via the env

How would I test this PR locally? Changing the API address in the env works fine, but I notice that there's issues with signing in and data not being fetched. Usually, I would comment out the env API URL lines on the Sign In page and next.config.js, but how would I do that in this PR?

@intisarosman1 I think the issue might the localhost address does not contain the same port value as the backend server.
So If the frontend .env file contains 3005 (API_URL=http://localhost:3005/api) then the backend listening port value should be 3005

Thank you @IsaacJrTypes, I was able to get it working!
