feat: Improve WinRM Security: Firewall, Encryption & Authentication

[csautter]

For simplicity, the current WinRM setup has several security measures disabled. This issue aims to evaluate and improve the security configuration to ensure production-grade protection.

Tasks / Evaluation Points:

• Assess whether the number of accessible ports can be reduced by refining the firewall configuration.
• Evaluate the feasibility of enabling WinRM security features such as transport encryption and certificate-based authentication.

Acceptance Criteria:

• WinRM security in production environments follows best practices and is as robust as possible.
• Development or reference configurations are not accidentally reused in production environments.
