Pull request overview

This PR refactors the ncproxy component to use HAProxy instead of nginx as the underlying proxy server. The change involves replacing nginx-specific configuration templates, updating the service logic, and adapting the Docker setup accordingly.

Key changes:

• Replaced nginx with HAProxy in the nproxy Docker container (Dockerfile and entrypoint)
• Refactored ncproxy configuration generation from nginx to HAProxy syntax
• Introduced a new logger subsystem to receive HAProxy syslog messages via Unix socket
• Updated CLI to use --haproxy-dir flag with backward-compatible --nginx-dir alias
