Enable background workers to scale to zero

[tjementum]

Summary & Motivation

Allow background workers to scale to 0 by changing Microsoft.NET.Sdk.Worker to Microsoft.NET.Sdk.Web and Host.CreateApplicationBuilder to WebApplication.CreateBuilder. This hack enables workers to expose a minimal API, allowing Azure Container Apps to monitor ingress and scale the Container Apps to zero. The Bicep infrastructure has been updated to enable internal ingress.
