feat: Fix loan API type assertion and complete core loan features

- Resolve interface conversion panic in loan handlers by correcting
  user type assertions from *models.User to models.User
- Finalize loan management API integration with frontend components
- Implement remaining loan calculation logic and CRUD operations
- Connect loan display components to backend APIs as per Phase 3
- Update project status in README.md to reflect completed loan features
- Add CORS middleware configuration for frontend-backend communication

This commit completes core loan management functionality and fixes critical
type safety issues in the API handlers, enabling proper user context handling.
