feat: Implement secure random password generation for Prometheus
- Add generate-monitoring-secrets.sh script that creates random passwords - Auto-configure Prometheus with generated password hash - Auto-configure Grafana datasource with same random password - Update setup-server.sh to include monitoring setup - Remove hardcoded Prometheus credentials from repository - Keep Grafana default admin password for user configuration - Generate secure 16-character random passwords for each deployment - Store generated credentials in monitoring/.env.generated (gitignored)
