Service util setup

Issue Number(s): #8

What does this PR change and why?

Checklist

• A service util layer has been created which exports TS functions that handles all HTTP requests and responses
• These exported functions are imported with the frontend pages and components that utilize them, and work, facilitating communication between the frontend and backend.
• A separate file is created for each endpoint: one for auth, one for pets

Critical Changes

• Created fetchAPI.ts to handle api calls to the backend
• Created individual files for auth and pets along with the required calls

Great work overall! I just left some small comments. Thanks for all your hard work!

UserId is a number in authService, while a string in petService, is this intended? Also should fetchService also take the 'HEAD' and 'OPTIONS' request methods? Should the response also include the header?

Looks great Kenny!
