fix: resolve all PSScriptAnalyzer warnings and compliance issues

- Replace Write-Host with Write-Information in Test-NoRebootCompatibility.ps1
- Remove trailing whitespace from all PowerShell scripts
- Add UTF-8 BOM encoding for Unicode compliance
- Ensure all scripts pass PSScriptAnalyzer validation with no warnings or errors
- Maintain professional PowerShell coding standards

All PowerShell scripts now fully compliant with PSScriptAnalyzer requirements.
