If CA is unavailable, Auditing/ESC6/ESC11 Reporting is Unclear

[jakehildreth]

Describe the Bug
If Locksmith cannot get data from certutil.exe (either from network issues or limited privileges), Locksmith reports Auditing/ESC6/ESC11 Issue as "CA Unavailable" and Fix as "N/A". This is not helpful.

Steps To Reproduce

1. Lock down the use of certutil by low-privileged users.
2. run Locksmith.

Expected Behavior
If CA is unavailable, Locksmith should return the reason why it's unavailable.

Environment

• Locksmith Version: 2025.1.14 (unreleased)
• OS: Windows Server 2019
• PowerShell Version: Windows PowerShell 5.1
• PowerShell Host: VS Code Terminal
