added non-activity section

[Yashaswini-K-P]

Description

This PR improves the leaderboard experience by resolving arbitrary ranking assignments for users with 0 scores. It handles zero-score behavior differently across tabs to match the terminal-style UI theme and prevent empty layouts:

• Overall Leaderboard: Completely removes users with an overall score of 0 from the competitive ranks and displays them in a separate "No activity yet" section.
• Daily/Weekly/Monthly Leaderboards: Keeps zero-score users visible at the bottom to ensure the UI stays active, but omits their rank numbers, replacing them with a non-competitive -- delimiter.

• Integrated changes with existing pagination, filtering/search logic, and mobile layouts.

I've tested the changes locally and the implementation looks good overall, especially the separate non-activity section in the Overall leaderboard.

There are just a couple of behavior adjustments I'd still like before merging:

• The separate "No activity yet" section shouldn't exist only in the Overall tab. Since the same never-active users are present across all leaderboard datasets, this section should appear consistently across Daily/Weekly/Monthly as well.

• The -- non-competitive rank placeholder behavior was mainly intended for users who temporarily have a 0 score in a specific timeframe leaderboard, but still have activity/score in the Overall leaderboard. In other words:

  • users with no activity at all → move to the separate non-activity section,
  • users active overall but currently 0 in Daily/Weekly/Monthly → keep in the normal leaderboard flow with -- instead of a rank.

• In the stats section:

  Total Users: 90 | Showing: 26-50 | Page: 2/4
  

  I'd still prefer Total Users to represent the complete registered leaderboard size rather than only active users.

  For example, if there are 107 total users and 17 are never-active users, I think the count should still display 107 instead of 90 since those users are still searchable and still rendered later in the page under the non-activity section.

I've added a few changes to improve the mobile view of the leaderboard after adding this feature, and everything looks good now.

My only concern at this point is the sync script changes, since I don't think those are really required here, the frontend is already handling this behaviour correctly on its own

Since the frontend is already handling this, I don't think adding the same logic again inside the sync script is really necessary
