Create the primary functionality for Authentication

- [x] Create user
- [x] Create userTypes
- [ ] Generate Authtoken (Auth and refresh)
- [ ] GEnerate Auth token from refresh token

The issue describes implementing token generation and refresh functionality. Start by examining the existing user and userTypes creation code to understand the data models. Look for authentication-related files or middleware. Implementing token generation will likely involve a library like jsonwebtoken and setting up routes for token issuance and refresh. Verify the work by testing the token flow end-to-end.
