fix(load-balancer): implement missing HAProxy reload and sanitize output handling

Implement the `reload_restart` method in `LoadBalancerConfig` to ensure proper HAProxy configuration management. Additionally, enhance SSH command execution by sanitizing and logging outputs effectively. This ensures robust handling of HAProxy configurations and improves debugging capabilities through trace-level logs.
