Backport of #25557 to release/v7.5.12

Impact
REQUIRED: Choose either Tooling Impact or Customer Impact (or both). At least one checkbox must be selected.
Tooling Impact
Customer Impact
Fixes #25556, where Show-Command lacks the module import helper behavior and can run in unsupported restricted remoting sessions instead of returning a clear terminating error.
Regression
REQUIRED: Check exactly one box.
The Show-Command behavior regression was introduced by #20593.
Testing
The backport cherry-picked cleanly and passes git diff --check and HelpErrors.resx XML parsing. Builds of the two affected projects were attempted after restoring dependencies but were blocked in an unrelated dependency project by missing generated DotNetEventingStrings resources in Microsoft.PowerShell.CoreCLR.Eventing.
Risk
REQUIRED: Check exactly one box.
Medium risk because this changes Show-Command behavior and module-import script generation, but the changes are limited to the graphical host helper and an explicit restricted-session guard. The backport cherry-picked cleanly.
