Pull Request Overview

This PR adds support for configuring a messaging endpoint as an alternative to deploying an Azure Web App for Agent 365 agents. This allows developers to use externally hosted agents while still registering them with the Agent 365 platform.

Key Changes

• Added MessagingEndpoint property to Agent365Config as an optional alternative to WebAppName/AppServicePlanName
• Modified validation logic to make App Service fields optional when MessagingEndpoint is provided
• Updated configuration wizard to prompt users whether to create a Web App or provide an external messaging endpoint
• Changed AppServicePlanSku default from "B1" to empty string to align with optional App Service fields

• This assignment to messagingEndpoint is useless, since its value is never read.

        var messagingEndpoint = Get("messagingEndpoint");
