feat: configure blockchain services on correct ports

✅ Blockchain Services Port Configuration
- Blockchain HTTP API: Port 8005 (new service)
- Blockchain RPC API: Port 8006 (moved from 8007)
- Real Marketplace: Port 8009 (moved from 8006)

✅ New Services Created
- aitbc-blockchain-http.service: HTTP API on port 8005
- blockchain_http_launcher.py: FastAPI launcher for blockchain
- Updated environment file: rpc_bind_port=8006

✅ Port Reorganization
- Port 8005: Blockchain HTTP API (NEW)
- Port 8006: Blockchain RPC API (moved from 8007)
- Port 8009: Real Marketplace (moved from 8006)
- Port 8007: Now free for future use

✅ Verification
- Blockchain HTTP API: Responding on port 8005
- Blockchain RPC API: Responding on port 8006
- Real Marketplace: Running on port 8009
- All services properly configured and operational

🚀 Blockchain services now running on requested ports!
