👍 Implement Like / Vote Feature #10

Allow users to like/vote posts to show appreciation and support.
This feature contributes to the Leaderboard rankings for both authors and posts.

✅ Tasks

• Database Integration

  • Implement Vote model linking User and Post.
  • Ensure one user can only like a post once (unique constraint).
  • Store timestamps for potential future analytics.

• UI/UX

  • Add like button (toggle state: liked / not liked).
  • Show total number of likes on each post.
  • Provide real-time feedback (optimistic update or re-fetch).

• Backend / Fullstack Logic

  • Implement server-side action for toggling like/unlike.
  • Ensure only authenticated users can vote.
  • Integrate vote count into leaderboard logic.

• Testing & QA

  • Add unit tests for vote creation & deletion.
  • Add integration tests for like toggle flow.
  • Test UI interactions (like, unlike, state updates).

🏁 Acceptance Criteria

• Authenticated users can like/unlike posts.
• Total like count is displayed and updated correctly.
• Each user can only like a post once at a time.
