Login check

[jpuka01]

Describe your changes

We implemented a check that validates if a user exists in our MongoDB database by checking the username and password. If the user credentials during logging in exists, the API sends out a successful login message. Otherwise, the API will catch whether the name or password of the user is invalid and appropriately send out an error message based on the catch. We also ensured a check whether our endpoint faced any database server related issues as well as commented debug prints for added debugging.

Testing done and screenshots (if relevant)

1. Checked if both username and password matches any single user in the database and returned a successful login.
2. Checked if any of the username or password field does not match any existing user in the database, then return a specific error message.
3. Ensured our endpoint is connected to our database server.

Nice job implementing the login check! Everything looks great, just a heads up that all of our endpoint routes are going to be prefixed with /api/. This is to keep the API routes separate from our frontend website routes which isn't a problem right now because we're using different ports for frontend and backend, but will be a problem when we deploy.
