[Feature]: ELUSoC_2026 — Leaderboard page has no search or filter — users cannot find themselves in large communities

[Babin123456]

Problem

The LeaderboardPage fetches up to 50 entries and displays them in a table, but provides no search box or filter controls. In communities with more than ~20 members, users cannot quickly locate a specific player or filter by role.

Current Behavior

• The leaderboard renders a flat table with no way to search or filter.
• Users must visually scan all 50 rows to find a specific username.
• The "Your rank" pill at the top only appears when the logged-in user is in the top 50 — no way to search for others outside the list.

Why This Improvement Is Needed

• Large communities (50+ members) need search to find specific participants.
• Admins/Moderators often want to filter the leaderboard by role (e.g., "show all Members").
• This is a standard UX feature expected in any ranking system.
• The data is already fetched client-side, so no additional API calls are needed.

Proposed Solution

Add a search box and role filter pills above the leaderboard table:

1. A text input that filters entries by username (case-insensitive substring match).
2. Role pills (All / Admin / Organisation / Moderator / Event Staff / Member).
3. A result count label shown when a filter is active.
4. The top-3 podium is hidden when a filter is active (rankings would be misleading).
5. An empty state is shown when no players match the current filter.

All filtering is client-side with useMemo — no new API endpoints required.

Expected Outcome

• Users can type a username to instantly locate a player in the leaderboard.
• Admins can click a role pill to view only Members or only Moderators.
• The UX is consistent with the existing Shop page's search + category filter pattern.

Additional Notes

• No backend changes required.
• The podium correctly reappears when filters are cleared.

Hi, I'd like to work on this issue. I'll add a client-side search box and role filter pills to LeaderboardPage with useMemo-based filtering, result count label, and empty state, as outlined above. Could you please assign it to me?
