Add complete simulation API layer for reward method comparison

Browse Source 
This completes Phase 3 of the simulation system implementation:

- Add comprehensive REST API endpoints for simulation data access
- Implement /v1/simulation/* routes with full CRUD operations
- Support JSON/CSV export for external analysis
- Add statistical comparison between old vs new methods
- Provide node performance history tracking
- Include proper error handling and response formatting
- Simplify simulation coordinator to remove unused complex return types
- Clean up dead code while maintaining all functionality
- Pass clippy with no warnings

The simulation API provides complete access to:
- Simulation epoch listing and details
- Method comparison analytics (old 24h vs new 1h)
- Node performance analysis across epochs
- Route reliability statistics
- Export capabilities for further analysis

All simulation data is persisted and accessible via REST endpoints.
