[backend] Implement Agent Dashboard: Float Utilization, Earnings, Borrower Portfolio

Description: Agents need real-time dashboard showing: current float utilization %, projected earnings, borrower portfolio health, pending settlements, collateral ratio.

Impact: Agent retention; operational efficiency; proactive risk management; platform stickiness.

Suggested Fix:

1. Add GET /api/agents/dashboard endpoint
2. Aggregate: float utilization (current/limit), earnings (daily/weekly/monthly), borrower count, overdue rate, collateral ratio
3. Add WebSocket updates for real-time metrics
4. Create frontend dashboard page in frontend/src/app/[locale]/agent/dashboard
5. Add caching with 30s TTL for expensive aggregations

Points: 150
Type: enhancement

Definition of Done

• Dashboard endpoint implemented with all metrics
• WebSocket real-time updates
• Frontend dashboard page with charts
• Caching with 30s TTL
• Implementation complete following component patterns
• Code review passed
• Documentation updated if needed
• All necessary CI checks passed

I’d like to work on this issue. I have experience working with Stellar and Web3 projects, including Soroban contracts and frontend/backend integrations. I’ll go through the existing code first, make the required changes, and test everything properly. I’m ready to start.
