Add Real-Time Ideas Feed with Subscription-Based Updates

[Divineifed1]

Component: app/page.jsx, lib/soroban-contract.ts
Type: Feature
Priority: High

Description:
The platform currently shows static placeholder content. Implement a real-time ideas feed that subscribes to blockchain events and updates the UI when new ideas are created or votes are cast.

Tasks:

• Implement SSE (Server-Sent Events) or WebSocket connection for real-time updates
• Create event listeners for create_idea and vote_idea contract events
• Add optimistic UI updates for better user experience
• Implement pagination/infinite scroll for large datasets
• Add filter persistence across page refreshes

Acceptance Criteria:

• New ideas appear without page refresh
• Vote counts update in real-time
• Performance remains smooth with 1000+ items

Hi, I'd like to work on this feature.

My implementation plan is:

• Implement a real-time update layer using SSE or WebSockets, depending on the project's architecture and deployment requirements.
• Create listeners for create_idea and vote_idea Soroban contract events and sync them with the frontend state.
• Add optimistic UI updates so newly created ideas and votes appear immediately while transactions are being confirmed.
• Implement pagination and/or infinite scrolling to efficiently handle large datasets.
• Persist user-selected filters across page refreshes using URL parameters or local storage.
• Optimize state management and rendering performance to ensure smooth operation with 1000+ items.

Before submitting the PR, I'll verify that:

• New ideas appear without requiring a page refresh.
• Vote counts update in real time across connected clients.
• Filter selections persist after reloads.
• Performance remains responsive with large numbers of ideas.

Please assign this issue to me if it is available.
