docs: refactor workflow with script references and add mempool RPC endpoint

📋 Workflow Documentation:
• Replace inline service optimization with 15_service_optimization.sh reference
• Replace inline monitoring setup with 16_monitoring_setup.sh reference
• Replace inline security hardening with 17_security_hardening.sh reference
• Add production readiness validation with 18_production_readiness.sh
• Consolidate scaling and load balancing script references
• Remove duplicate integration

+Network Security:
+- Firewall configuration: Skipped as requested
+- Network security: Basic configuration completed

+SSH Hardening:
+- Root login: Enabled (development mode)
+- Password authentication disabled
+- Max authentication attempts: 3
+- Session timeout: 5 minutes

+Access Control:
+- User creation: Skipped as requested
+- Sudo configuration: Skipped as requested
+- Basic access control: Completed

+Monitoring:
+- Security monitoring script created
+- Hourly security checks scheduled
+- Logs stored in /var/log/aitbc/security.log

+Recommendations:
+1. Use SSH key authentication only
+2. Monitor security logs regularly
+3. Keep systems updated
+4. Review access controls regularly
+5. Implement intrusion detection system
