fix: document clipboard history dependency

[Minlor]

Description

Updates the Touch Keyboard and Handwriting Panel Service description to explicitly state that disabling the service also disables Windows clipboard history (Win+V).

The previous wording described the setting as safe on desktop systems without touch, pen, or gamepad hardware. That could mislead desktop users who rely on clipboard history, so the description now lists clipboard history with the other affected Windows Input Experience features.

Both the catalog fallback text and the English UI localization are updated so the warning is visible in the application.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Code refactoring (no functional changes)
• Performance improvement
• Build/CI configuration change

Related Issues

Follow-up to #374 and #590.

Testing Performed

• Unit tests added/updated
• Manual testing performed
• Regression testing performed

Validation performed:

• dotnet build src/Winhance.Core/Winhance.Core.csproj --configuration Release --no-restore passes with zero warnings.
• All 29 localization JSON files parse successfully and retain the same key set as en.json.
• Verified that both the catalog fallback and English UI localization include Windows clipboard history (Win+V).
• git diff --check passes.

The localization integration-test project could not be compiled locally because the machine does not have the Windows 10 UAP SDK 10.0.19041.0 Platform.xml required by the unrelated WinGet interop project.

Additional Notes

An earlier source-only wording change for #590 did not update the localized UI string. This change keeps the catalog fallback and the displayed English localization in sync.
