Web tokens auth

[aradradev]

In this milestone we have implemented the following features:

• Created get post and delete request for the user

• Created Cars Controller::API

• Generated and added the features for the API

• Tested the API on Postman

• Authentication for user API:: http://localhost:3000/api/v1/login/ Explanation: This API will make sure that a user logs in to access the page, and it will give secure web tokens and this token can be used to make requests for cars and registrations.

• token: Authorization type: Bearer.

• Users API:: http://localhost:3000/api/v1/users/ Explanation: how this API could be used to make a post request and get a new user it uses the last web token to create a new user.

• Cars API:: http://localhost:3000/api/v1/users/user_id/cars :: API::In-progress...

Explanation and example to use this API::
`import jwt from 'jsonwebtoken';

// Assuming the token is stored in a variable called 'token'
const userToken = 'Bearer eyJhbGciOiJIUzI1NiJ9.eyJ1c2vyX2lkIjoxfQ.SRykN3CF-soWGfrD33q0Tme3a--wmGQ5Vl9dohn_fz4';

// Remove 'Bearer ' from the token
const token = userToken.replace('Bearer ', '');

try {
  const decoded = jwt.decode(token);
  const userId = decoded.user_id;
  console.log(`User ID: ${userId}`);
} catch (error) {
  console.error('Error decoding token:', error);
}
You can then use the userId variable to construct the URL for the API requests, like http://localhost:3000/api/v1/users/${userId}/cars. This way, the front end can make requests on behalf of the user while ensuring that each user can only access their own data.

`

Please review the API above and make sure that we can make GET, POST, and DELETE requests.

@hmunish Do not merge this branch until I finish the full implementation of the auth user

@aradradev, great job implementing user authentication & endpoints for cars. It's time to merge it.

🟢 User authentication working fine.
