[Real-Time] Live WebSocket Updates for Market Map & Leaderboard

[jpdevhub]

Integrate Supabase Realtime (or FastAPI WebSockets). When a new scan is uploaded and a vendor's trust score changes, the frontend Market Map and Leaderboard should update instantly without the user needing to refresh the page.

Hi @jpdevhub,

I would like to work on this issue under SSoC'26.

I have experience with React and backend integration, and I am interested in implementing real-time WebSocket updates for the Market Map and Leaderboard to ensure data is updated instantly without requiring page refreshes.

Could you please assign this issue to me?

Thank you!
