Added Controller for getArticle and getArticlebyID

[richartothman]

We have created a controller for the articles get function, but there is a slight problem, the GET request does not return an error, however, get article returns an empty array [] and get article by id returns nothing. We are not sure if our function is wrong.

You can try to improve the readability by re-implementing the post-processing steps instead of just copy and paste.

1. Please find out how we fetch data from the DB (filter and option) and how we process the result after getting the data in v1.
2. I noticed you used console.log to print some information, but in practice, you should use logger. And since we haven't decided what should be logged, you could simply remove all console.log.
3. Keep the Service as general as possible because it might be called by various functions.
4. It is better to integrate the code related to the article into ArticleModule (please create a new file), and import it to AppModule.

It's almost complet.

To ensure that your code is correct, try writing some unit tests for the controller and end-to-end tests for the APIs. If you're unsure how to proceed after reading the documentations below, you can reference the codebase in /test (though it's not entirely complete) or ask ChatGPT for assistance.
