feat(windows): disable Surface Laptop power button

[DevSecNinja]

Accidental power-button presses are easy on Surface Laptop keyboards because the button sits next to Delete. This prevents those presses from suspending or shutting down opinionated-profile workstations.

Changes

• Detect Microsoft Surface Laptop and Surface Laptop Studio hardware before changing system power settings.
• Set the active plan's AC and battery power-button actions to Do nothing in the Windows full profile.
• Leave non-Surface devices and light-profile installations unchanged.
• Add isolated Pester coverage for hardware detection, powercfg arguments, WhatIf, and failure propagation.
• Document the opinionated Windows behavior.

Validation

• Targeted Pester suite: 10 tests passed.
• Chezmoi configuration, script, and dry-run apply checks passed.
• PSScriptAnalyzer and pre-commit hooks passed.
