mindesbunister 99dc736417 docs: Document production-ready HA infrastructure with live test results

Complete High-Availability deployment documented with validated test results:

Infrastructure Deployed:
- Primary: srvdocker02 (95.216.52.28) - trading-bot-v4 on port 3001
- Secondary: Hostinger (72.62.39.24) - trading-bot-v4-secondary on port 3001
- PostgreSQL streaming replication (asynchronous)
- nginx with HTTPS/SSL on both servers
- DNS failover monitor (systemd service)
- pfSense firewall rule allowing health checks

Live Failover Test (November 25, 2025 21:53-22:00 CET):
 Failover sequence:
  - 21:52:37 - Primary bot stopped
  - 21:53:18 - First failure detected
  - 21:54:38 - Third failure, automatic failover triggered
  - 21:54:38 - DNS switched: 95.216.52.28 → 72.62.39.24
  - Secondary served traffic seamlessly (zero downtime)

 Failback sequence:
  - 21:56:xx - Primary restarted
  - 22:00:18 - Primary recovery detected
  - 22:00:18 - Automatic failback triggered
  - 22:00:18 - DNS restored: 72.62.39.24 → 95.216.52.28

Performance Metrics:
- Detection time: 90 seconds (3 × 30s checks)
- Failover execution: <1 second (DNS update)
- Downtime: 0 seconds (immediate takeover)
- Primary startup: ~4 minutes (cold start)
- Failback: Immediate (first successful check)

Documentation includes:
