refactor: remove redundant startup script and use systemd services directly

SystemD Simplification - Complete:
✅ REDUNDANT STARTUP SCRIPT REMOVED: Eliminated unnecessary manual startup script
- setup.sh: Removed create_startup_script function entirely
- Reason: SystemD services are used directly, making manual startup script redundant
- Impact: Simplified setup process and eliminated unnecessary file creation

✅ FUNCTIONS REMOVED:
🗑️ create_startup_script: No longer needed with systemd services
🗑️ /opt/aitbc/start-services.sh: File is no longer created
🗑️ aitbc-startup.service: No longer needed for auto-start

✅ UPDATED WORKFLOW:
📋 Main function: Removed create_startup_script call
📋 Auto-start: Services enabled directly with systemctl enable
📋 Management: Updated commands to use systemctl
📋 Logging: Updated to use journalctl instead of tail

✅ SIMPLIFIED AUTO-START:
🔧 Before: Created aitbc-startup.service that called start-services.sh
🔧 After: Direct systemctl enable for each service
🎯 Benefit: Cleaner, more direct systemd integration
📁 Services: aitbc-wallet, aitbc-coordinator-api, aitbc-exchange-api, aitbc-blockchain-rpc

✅ UPDATED MANAGEMENT COMMANDS:
📋 Before: /opt/aitbc/start-services.sh
📋 After: systemctl restart aitbc-wallet aitbc-coordinator-api aitbc-exchange-api
📋 Before: tail -f /var/lib/aitbc/logs/aitbc-*.log
📋 After: journalctl -u aitbc-wallet -f
🎯 Purpose: Modern systemd-based service management

✅ CLEANER SETUP PROCESS:
1. Install systemd services (symbolic links)
2. Create health check script
3. Start services directly with systemctl
4. Enable services for auto-start
5. Complete setup with systemd-managed services

✅ BENEFITS ACHIEVED:
✅ Simplicity: No unnecessary intermediate scripts
✅ Direct Management: Services managed directly by systemd
✅ Modern Practice: Uses standard systemd service management
✅ Less Complexity: Fewer files and functions to maintain
✅ Better Integration: Full systemd ecosystem utilization

✅ CONSISTENT SYSTEMD APPROACH:
🔧 Service Installation: Symbolic links to /etc/systemd/system/
🔧 Service Management: systemctl start/stop/restart/enable
🔧 Service Monitoring: systemctl status and journalctl logs
🔧 Service Configuration: Service files in /opt/aitbc/systemd/

RESULT: Successfully removed redundant startup script and simplified the setup process to use systemd services directly, providing a cleaner, more modern, and maintainable service management approach.
