Support Microsoft Entra auth in Data Transfer connections

[alex-bochkov]

Motivation

• Ensure the Data Transfer UI and related connection helpers honor Microsoft Entra / Azure AD authentication modes so interactive/MFA and other Entra flows work when selecting source/target SQL Server connections.

Description

• Switched SQL client using directive in the Data Transfer window to Microsoft.Data.SqlClient to allow Entra-related connection-string/authentication features. (file: DataTransfer/DataTransferWindowControl.xaml.cs)
• Centralized and extended authentication handling in ScriptFactoryAccess by adding reflection-based extraction of authentication metadata and helper functions: GetAuthenticationMode(object), AddPropertyValue, ApplyAuthentication, GetSqlAuthenticationMethod, ContainsAny, ShouldSendPassword, and an updated interactive-detection ShouldUseMicrosoftEntraInteractive to decide when to use SqlAuthenticationMethod.ActiveDirectoryInteractive. (file: Modules/ScriptFactoryAccess.cs)
• Updated object-explorer connection string construction to call the new ApplyAuthentication flow and preserve Encrypt/TrustServerCertificate when available, while avoiding accidental IntegratedSecurity=True for Entra interactive/MFA flows. (file: Modules/ScriptFactoryAccess.cs)
• Broadened token/keyword detection to recognize both “Microsoft Entra” and common Azure AD/Active Directory authentication keywords so various connection string/property patterns are handled.

Testing

• Ran git diff --check to verify no whitespace/patch errors, which completed with no issues.
• Attempted dotnet build AxialSqlTools/AxialSqlTools.sln but the dotnet CLI is not available in the environment so a full build could not be executed.
