Support explicit bind address for worker log server

[ananich]

Problem

Currently, the Airflow worker log server (serve_logs.py) is hardcoded to bind to all available interfaces (0.0.0.0 or [::]) via socket.has_dualstack_ipv6(). This exposes port 8793 to the entire network by default, creating a potential security risk where task logs could be intercepted or scanned by unauthorized entities.

Proposed Change

This PR modifies the log server initialization to respect the WORKER_LOG_SERVER_HOST configuration variable. If this variable is set (e.g., to 127.0.0.1), the server will bind specifically to that address. If not set, it falls back to the existing dual-stack wildcard logic to maintain backward compatibility.
