Migrates deprecated ADAL (Microsoft.IdentityModel.Clients.ActiveDirectory) to MSAL (Microsoft.Identity.Client) for Azure AD authentication. Use ONLY when Microsoft.IdentityModel.Clients.ActiveDirectory has been flagged as obsolete or deprecated and must be replaced — not for version-bump scenarios where ADAL is still supported.
