Remove deprecated AzureAD module dependency from build pipeline

[givinalis]

Problem

The 1es-EntraPowerShell-PR pipeline is failing at the Install Dependencies Entra step because it attempts to install the AzureAD and AzureADPreview modules from the PowerShell Gallery. These modules have been deprecated by Microsoft and are no longer available for download.

Solution

Instead of dynamically importing the deprecated modules to discover their command lists, the build now uses the existing static mapping files (AzureADToEntraMapping.json and AzureADPreviewToEntraBetaMapping.json) as the source of truth for AzureAD command names.

Changes

• build/Install-Dependencies.ps1: Skip installing the deprecated source module; only install Microsoft.Graph destination modules
• src/Get-MissingCmds.ps1: Use mapping file keys as the command list instead of importing the module
• src/CompatibilityAdapterBuilder.ps1: Skip Import-Module of source module in Configure(); add fallback in GetModuleCommands() to read from mapping files when module is unavailable

Validation

• Verified Get-MissingCmds returns the correct 18 missing commands for AzureAD and 11 for AzureADPreview (matching previous behavior)
• Existing unit tests continue to pass
• No behavioral changes to the generated modules

Test-EntraScript uses the $script:MISSING_CMDS. This is a cmdlet that some customers still use (see the issue below). We need a way to map $script:MISSING_CMDS without relying on the AzureAD modules.

Thanks for the feedback @KenitoInc! This is already handled by the fix. The Get-MissingCmds function now reads the command list from the static mapping files (AzureADToEntraMapping.json / AzureADPreviewToEntraBetaMapping.json) instead of importing the deprecated AzureAD module. Commands with empty/null values in the mapping files are identified as unsupported which is the same set previously discovered by importing the module.

I've verified the built module bin/Microsoft.Entra.psm1 correctly populates $script:MISSING_CMDS with all 18 unsupported commands, so Test-EntraScript will continue to work correctly for customers.

The mapping files are now the single source of truth so any future updates to supported/unsupported commands just need to update those JSON files.
