Fixed the CORS config to be working correctly with the frontend
Browsers will send an OPTIONS request before doing a CORS request and the backend wasn't properly configured for that, resulting in the frontend not being able to communicate with the backend at all. I could've keep using gin-contrib/cors but I believe rs/cors to be better, especially with its debug option that will output useful header information to the console.
Switched the json model binding to camelCase to match the frontend's style
