feat: Add user profile page and link leaderboard entries to /user/:username

[Yashaswini-K-P]

Description:

Currently, student names on the leaderboard are displayed as static text elements. To improve platform engagement, navigation, and detailed data analysis, we need to make names clickable. Clicking a user's name should take them to a clean, dynamic profile route (/user/:username) where their specific LeetCode activity, stats, and historical metrics are isolated.

I would love to work on this pls assign me!!!

This is definitely a direction we want eventually, but I think this should stay blocked for now until the /user/:username page becomes a bit more mature feature-wise and visually.

At the moment the profile page is still under active development with several planned features still pending, so directly linking leaderboard usernames there right now may lead to an incomplete experience.

Marking this as blocked for now until the user profile page implementation stabilises further.

Thanks for the update, @jagdish-15. Completely understand keeping it blocked until the profile page matures. I'm very interested in working on this linking feature once it's stabilized—please feel free to tag or assign me when it's ready for development!
