Implement back-end support for favorite movies list feature

[skau811]

This Pull Request introduces few additions to the backend to support the functionality of adding, viewing, and editing favorite movies for users:

Server-Side Endpoints

• New endpoints have been added to handle requests related to the favorite movies list.

User Schema Updates

• The User schema has been extended with a new favorites array. This array holds the IDs of movies that users mark as favorites, enabling persistent storage of user preferences.

Instance Methods in userModel

• Relevant instance methods have been integrated into userModel to facilitate database write operations.

With these additions, the backend now has the relevant functions to incorporate the favorite movies list feature, thereby progressing towards the closure of #53 .

The testing of the endpoints was done using POSTMAN. Below are the requested screenshots which show the relvant requests and the state of the user document as a result of those interactions:

Background : The screenshots below are the result of the interactions with the user document with lightYG as the username, all the requests to the endpoints include the authorization token in the header (generated during login/signup), and take place using this token.

For further context:
