P2 Badge Propagate the icacls failure before reporting completion

When icacls returns nonzero—for example because the directory ACL cannot be modified—this new throw still does not make the tweak fail: Invoke-WinUtilScript.ps1:32-49 catches the resulting runtime exception without rethrowing or returning failure, after which Invoke-WinUtilTweaks.ps1:84 unconditionally logs that the tweak completed. Fresh evidence in the hardened version is that the newly added exit-code check is therefore swallowed by the existing wrapper, so callers can still treat an unapplied block as successful; propagate a failure result so completion is not reported.

This is the standard execution model across all WinUtil tweaks. Invoke-WinUtilScript catches runtime exceptions so errors are logged without crashing the runner or aborting other queued tweaks. Propagating tweak failure status to Invoke-WinUtilTweaks would require changes to the core execution engine across the entire codebase, which is out of scope. You can safely disregard this!
