.SYNOPSIS
    Pester tests for OutputFormat parameter and report generation functions.
 
.DESCRIPTION
    Validates:
      - The -OutputFormat ValidateSet on Invoke-AzureScout (All/Excel/Json/Markdown/AsciiDoc/MD/Adoc/PowerBI)
      - Export-AZSCMarkdownReport function exists and generates a .md file
      - Export-AZSCAsciiDocReport function exists and generates a .adoc file
      - Export-AZSCPowerBIReport function exists and generates a CSV bundle
    No live Azure authentication is required.
