Add option to revert previous changes to windows defaults

[Raphire]

This adds the ability to revert changes back to Windows defaults using the provided undo files. This is still a WIP, the current implementation only supports reverting changes for the current user.

[Copilot]

Pull request overview

Adds an “undo/revert” capability to Win11Debloat so previously applied tweaks can be reverted back toward Windows defaults, leveraging per-feature undo metadata in Config/Features.json and exposing the workflow via both CLI and the GUI home screen.

Changes:

• Introduces -Undo mode and supporting helper logic to execute undo-capable features via RegistryUndoKey/UndoAction.
• Adds a new GUI “Revert previous changes” entry point and modal to select revertable settings and apply them.
• Updates feature Action/Label phrasing for better “Action + Label” composition and adds an undo .reg file for Windows Suggestions.

Scripts/CLI/PrintPendingChanges.ps1:9

• CreateRestorePoint is printed using only the feature Label, but this PR changed that label to "a system restore point", resulting in output like "- a system restore point". PrintPendingChanges should include the Action as well (or restore a verb phrase label) so the CLI summary remains clear.

    if ($script:Params['CreateRestorePoint']) {
        Write-Output "- $($script:Features['CreateRestorePoint'].Label)"
    }

Scripts/CLI/PrintPendingChanges.ps1:15

• CreateRestorePoint is printed using only Features['CreateRestorePoint'].Label. After the Features.json change, the label is now just "a system restore point", so the CLI summary will render as "- a system restore point" (missing the verb). Consider printing Action + Label here (or using ApplyText) so the output stays grammatical and consistent with other entries.

    if ($script:Params['CreateRestorePoint']) {
        Write-Output "- $($script:Features['CreateRestorePoint'].Label)"
    }

Scripts/CLI/PrintPendingChanges.ps1:15

• CreateRestorePoint is printed using only Features['CreateRestorePoint'].Label. With the updated Features.json values (Action="Create", Label="a system restore point"), the CLI output becomes "- a system restore point" (missing the verb). Either keep the label as a full phrase again, or update this output to use Action + Label (and handle Action being null).

    if ($script:Params['CreateRestorePoint']) {
        Write-Output "- $($script:Features['CreateRestorePoint'].Label)"
    }
