Comment model

[JanosM99]

As a user of the platform, I want to be able to comment on posts and interact with other users' comments,

• Users should be able to write and post comments on any post within the platform.
• Each comment should have a text content field and be associated with the user who posted it.
• Users can see the author's name, profile picture, and the timestamp of each comment.
• Users should be able to edit and delete their own comments.
