feat: Add Windows Service hosting support

- Add Microsoft.Extensions.Hosting.WindowsServices package
- Add HostingOptions:UseWindowsService configuration flag to appsettings.json
- Configure Program.cs to optionally run as Windows Service based on config
- IIS hosting continues to work by default (UseWindowsService=false)
- Delete obsolete Worker.cs that was conflicting with ProfileManager
