feat: add blockchain info endpoints and client job filtering capabilities

- Add /rpc/info endpoint to blockchain node for comprehensive chain information
- Add /rpc/supply endpoint for token supply metrics with genesis parameters
- Add /rpc/validators endpoint to list PoA validators and consensus info
- Add /api/v1/agents/networks endpoint for creating collaborative agent networks
- Add /api/v1/agents/executions/{id}/receipt endpoint for verifiable execution receipts
- Add /api/v1/jobs and /api/v1/jobs/
