Add like system for blog posts

[huseynovvusal]

Implement a like system for blog posts to allow users to like and unlike individual posts. The feature should:

• Add an endpoint for liking and unliking posts.
• Track the number of likes per post.
• Ensure each user can only like a post once.
• Optionally, display the list of users who liked a post.

This will improve user engagement and interactivity on the blog API.
